Hey there Upper East Siders, Gossip Girl here. There's something new on the drama radar of Manhattan's elite…Spotted: N leaving B's looking depressed and tear-stained. No more smooth sailing for B and N? Gossip Girl wants to know, so you know I'll be watching.

Nate enters into the Waldorf residence and immediately draws Blair into a hug. He senses that she is stiff and there is a sense of tension in the air. He's felt it for months and tried to work through things because Blair is an amazing girl, but something is wrong—she's not the same girl she used to be.

"So, what's up? You said you wanted to talk. Is everything okay?" he asks nervously.

Blair sighs. "Everything's fine," she says as she grabs his hand and leads him into the parlor.

They sit on the couch in awkward silence. They both anticipated this moment for a while. They used to be so close, but a lot has happened which caused a wall to form in between them. Nat, looks around the room, finally puts all of his attention on a silent Blair, and grabs her hand.

"Blair, I know something is wrong. Something has been off in our relationship for a long time…"

Blair opens her mouth to say something, but Nate stops her, "Blair let me finish," he continues.

"Okay," she says in a voice just above a whisper.

"Things have been tense for a while. I understand that things have been hard with your parents divorce and Serena leaving for boarding school, but I think those things are gradually being resolved so we should focus on mending our relationship. I want things to go back to the way they were."

"I don't know if they can go back to the way they were, Nate," Blair says struggling to keep her composure after Nate's heartfelt plea.

"Why can't they, Blair? I love you, why can't we work through this?" he asks with watery eyes.

The brunette looks at him, unsure of what she should say. Nate beats her to the punch saying, "Don't you love me anymore?"

"Nate, I'll always love you…"

He exhales in relief, "What's the problem then?"

"I'm not in love with you."

...

Blair stood in the elevator of the Palace waiting for it to land on the floor where the van der Woodsens were staying during their house's newest makeover. She was anxious to tell Serena about her breakup because she wasn't really sure where they stood in their relationship. She wasn't even sure where she stood at this stage in her life. Is she gay? Is she ready to have a public relationship with Serena? She had a lot of questions and she would eventually have to come up with some answers.

Finally she entered the van der Woodsen suite, put down her jacket and handbag, and began searching for the blonde. She was pleasantly surprised when she walked past the kitchen and discovered Serena covered in flour from head to toe.

"Serena, what am I going to do with you?" she asks jokingly—catching Serena by surprise.

"Geez, B. You really know how too sneak up on someone," Serena replied.

"And what are you doing exactly? You are a mess," Blair said as Serena walked toward her.

"I'm making cookies…well, I'm attempting to make cookies," she said with a lopsided grin. "Hey, aren't you going to give me a hug?"

"Not until you clean up," Blair said with a sense of playful seriousness while backing away from the blonde.

Suddenly Serena ran towards the brunette, "Aw, but I was making you cookies. I think that deserves a hug from my Blair-Bear."

After a few minutes, Blair found herself cornered and was quickly swept up into a hug. She attempted to wriggle out of Serena's embrace, but found herself face to face with the blonde. "Ugh, Serena you are ruining my clothes," she said lightly before pressing her lips to the blonde's cheek.

Serena smiled and finally let go, "It's alright, B. You can borrow some of mine."

Laughing, Blair smirked, "Why, Miss van der Woodsen, it seems like you are trying to get me out of these clothes."

Blushing furiously, Serena dropped her gaze. She had no clue how she should respond to that. Well she knew what she wanted to say (YES!), but she knew that she couldn't.

Blair knew that she embarrassed the blonde so she continued, "So there's something I want to tell you, it's the reason why I came over actually."

Serena, fearing the worst, began to head back into the kitchen to check on the cookies, "Yeah, what's up?" she asked as she peeked into the oven.

"Serena," she said causing the blonde to look up. She walked over and leaned against the refrigerator.

"Okay, B. You have my full attention now."

Blair started to walk over to her, "I broke up with Nate," she said standing just a few inches from the blonde.

Serena unable to make coherent sentences due to the brunette's proximity only nodded and licked her lips.

Blair smiled after seeing the response she had on Serena and finally leaned forward capturing the blonde's lips. Serena did not hesitate; instead she began to ease Blair backward until the brunette hit the edge of a counter. She ended the kiss, quickly lifted Blair onto the counter, and began another series of passionate kisses. Placing her hands on Blair's hips, Serena slid her tongue into Blair's mouth—moaning at the sensation and taste. The two battled for dominance and got to know the contours of each other, only stopping when the need for oxygen became too great.

"Wow, that was amazing," Blair said as she tried to gather her breath.

Serena smiled at Blair and said, "I can't believe this is happening. You are…I can't even come up with words to describe how amazing you are."

Blair plants a chase kiss on Serena's lips then jumps off the counter, "Despite how much I want to kiss you right now, we need to talk."

Serena pouted, "I know. So what do we do know? Do I ask you out? Are we in a relationship?"

"I want to be with you, but…can we keep it between us for a while? I don't know if I'm ready for everyone to know and I don't want to throw it in Nate's face."

Serena smiled at the brunette's concern for her ex, "Of course, I don't want to rush you into anything you aren't ready for. You can set whatever pace you want."

Blair grabbed Serena's hand and pulled the blonde toward her, "Thanks," she said after giving the blonde a kiss.

"Mmm, I could get used to that," Serena said teasingly.

"Me too. So, where are my cookies?" she asked, nudging the taller girl slightly.

Serena laughed and pulled the brunette closer to her, "I'm not really concerned about the cookies," she says as she pulls the brunette into a kiss.

...

Well, it seems like the reign of B and N as king and queen of the Upper East Side is over. What caused the split? And what will happen in the aftermath? You know you love me…Gossip Girl.
