Alexis arrived at Beckett's apartment at 4 on the dot in her hand she held 2 dresses, one was Beckett's and the others was hers, stood directly behind her was Castle.

"Castle what are you doing here? You should be getting ready."

"Well since I was the one that got you the dress I wanted to see if you liked it."

"Castle just go and get ready, I promise that Alexis and Lanie will tell you how much I liked it."

"Well how about if I just said I missed you."

"You saw me 3 hours ago if not that."

Alexis moved from the doorway and headed towards the back room where they were getting ready. Lanie was stood in the kitchen grinning at Castle and Beckett.

"But I haven't given you a kiss in wow, a long time."

She reached for him and whispered in his ear. "And you will have to wait a little longer."

Castle pouted. "But I've missed you and now you are denying me a simple kiss."

"Yes I don't see a problem with it."

He walked through the door and grabbed Beckett by the waist pulling her to him. "Please, just one then I'll go and get ready."

"Castle you really do act like a 12 year old sometimes."

"But a really cute 12 year old."

She wrapped her arms around his neck and smiled. "Okay then just one."

He leaned down and bought his lips to hers, what was a quick kiss turned into a heated one. A few moments later they broke apart and Beckett shoved him out the door.

"Now go and get ready."

"Whatever you want."

She closed the door and leaned against it sighing to herself she closed her eyes.

"Girl that was H-O-T. HOT!"

Beckett opened her eyes and looked at Lanie. "Well I'm going to go and get ready now."

She walked into the back room and saw Alexis unzipping the bag that held her dress. "So where's my dress?" Alexis then pointed to the other side of the room.

Beckett could hardly hold her excitement she walked over and traced her finger down the length of the bag. "Come on girl, we are all dying to look at the dress just open it already."

Beckett bit her lip and reached for the top of the zip. She pulled it down to the bottom and then moved it to the bed. They all stared at it and Lanie was smiling. "Wow that's one beautiful dress. Simple but so elegant."

Beckett stared down at her dress and couldn't say anything, it was beautiful. It wasn't the type of dress that Castle usually went for but she loved it. She traced her finger over the material.

"Well go and try it on Kate." Alexis smiled.

She picked the dress up and moved to put it on, Lanie was already in her dress which was black and fit her perfectly. It ended just below her knees and she was wearing her black heels with it. Alexis then went to put on her dress which was a light blue colour and was the same design as Beckett's.

Beckett came back into the back room and both Alexis and Lanie smiled at her.

"That really suits you Kate."

"What can I say your dad knows how to shop. Which is a little worrying."

"Oh don't be worried, it's sort of nice."

Beckett smiled and looked at Lanie. "So what do you think?"

"Girl that man's a keeper."

She laughed and smoothed the dress over herself. "And don't I know it."

Meanwhile over at Castle's apartment he was pacing around the room.

"Dude you need to chill." Ryan laughed sitting on a stool and drinking a beer.

"Easy for you to say that."

"What's got you so worked up anyway?"

Castle looked at him, wondering whether or not he should tell them about his and Beckett's relationship, and the reason he was so worked up was because this was the first public outing that him and Kate were going to. He then decided that he could tell him later.

"Oh nothing, I'm just worried about this film. I mean what if it doesn't live up to everyone's expectations."

Ryan stood up walked over to Castle grabbed him by the shoulders and made him stand still.

"Dude just chill, take deep breaths."

"Okay then." Castle breathed in and out taking deep breaths, which seemed to help. "Right I think I'm all good now."

Ryan moved to the fridge and handed him a beer. "Here you go Castle, drink this."

Esposito then came in wearing his tuxedo, a dark blue, and a white shirt along with a dark blue tie.

"Well you are looking good tonight, anyone fancy?" Ryan grinned at him.

"Well you could say that."

"Oh you're hoping to take one of the celebrities home before Castle does."

"No although I'm hoping to take someone else home."

"Oh so it's someone who's going to be there. Anyone we know?"

"Well you could say that."

"Oh please tell."

"No."

"You know bro that's harsh."

"You'll find out soon enough." Esposito grinned.

Castle laughed and moved out of the kitchen. "Well I'm going to go and get ready." He walked up to his room and got out the black tuxedo he used for events like this. Reaching into the table beside his bed he got the box that he had been storing there for Beckett and put it in his pocket.

By 6 Lanie, Alexis and Kate were all ready and waiting for Castle to come pick them up. The phone buzzed and Beckett picked it up.

"Hello…thank you we'll be right down." She put the phone back down and grabbed her purse. "The men are here to pick us up."

"Well it's about time." Lanie laughed.

They all walked down to the lobby and Castle was stood waiting for them, he eyes lit up when he saw Beckett. She smiled at him and he walked towards them.

"You look amazing." He said to her.

She smiled even more and her eyes glistened. "Thanks."

They stared at each other for a moment when Lanie interrupted them. "Well thanks Castle we look nice to you know."

He stared at them and laughed. "Why I'm so sorry, you do look lovely." He then stared at Alexis and smiled. "You to pumpkin."

"Thanks dad." She blushed.

"Right so are we ready to go?" He clapped his hands together.

They all nodded and smiled. "Great the limo is waiting outside."

They all started when Castle stopped Beckett. "You guys carry on we'll catch up."

Lanie and Alexis shrugged and carried on. Castle stared at Beckett and smiled. "You really do look amazing."

She smiled and gave him a quick kiss. "And you look really amazing too."

"I have something for you." He smiled. He reached into his pocket and pulled out the Tiffany's box.

Beckett gasped. "Castle…"

"Beckett I just want to show you how much you mean to me and well it's just a little gift. Don't worry I didn't go overboard on it." He lightly laughed.

He handed the box to her and she slowly opened it. She saw the light shine off the pendant. "Castle…it's beautiful."

"Just like you." He whispered. He reached down and took it from it's box. He moved behind her and unclasped it. He moved her hair aside and it rested on her neck.

"So ready to go?" He kissed the spot on her neck where it met her shoulders.

"Yeah come on let's go." She grabbed his hand and entwined their fingers together. As they made their way to the car Esposito and Ryan's head popped out from the sunroof.

"Dude we totally knew it you and Beckett are totally dating."

"Boys sit in that car or you aren't coming tonight." Beckett laughed and she moved closer to Castle.

"Okay then." They got in the limo and sat down pouring themselves some of the champagne. Castle and Beckett got in and they smiled at each other.

"So…" Ryan started.

"Ryan shut up. I don't want to hear a word from you until we get to the premier."

Ryan nodded in response. Castle put his arm over Beckett's shoulder and Beckett rested her head on his shoulder.

"Awww you guys look so cute together." Lanie smiled.

They made small talk until they pulled up outside the red carpet, fans were screaming and reporters were outside taking pictures and interviews.

"So we all ready?" Castle grinned.

"Yeah." They all said together.

With that Castle opened the door and stepped out.
