(A/N: THX HEAPS FOR THE REVIEWS!!! Okay I said that this is set in two years stupid me I thought Jenny and Eric were fifteen now so with two years I wanted them to be seventeen lol but don't worry about it cause it won't affect much hopefully but yeah I'm glad you like the story)

"I have a what?" Blair asked shocked

"You have a sister she is two years younger than you"

"Woah start from the beginning like why do I have a sister? Why isn't she living with us? And why didn't you tell me?"

"Okay well technically she is your half sister"

"Meaning it's not daddy's"

"Yes um when you were two your father and I had a huge fight and well I just needed to be away from him that night…So I went out with Lily and well I met a man I was drunk I didn't know what I was doing and one thing led to another and well I was pregnant"

"Wait a minute is this why you went away for five months?"

"Yes when I was four months pregnant I started to show and I told your father but we didn't want you to know because I knew I couldn't keep the baby"

"Why?"

"It was an accident and the father wanted to take her in so when I had the baby he took her in and she's been living in New Mexico"

"I can't believe you would keep something like this from me mother I should've known earlier"

"We were a perfect family this scandal could've ruined us"

"Oh so you're saying my sister could've ruined your reputation god mother how can you say that?"

"Blair control yourself here's more…Whenever I travel well I'm not working as long as it seems I take an extra month to visit her"

"Has dad ever met her?"

"No but he will soon her father just died Blair the past couple of years he's been suffering from cancer and well he wasn't rich she has no where else to live so she's going to be staying with me now"

"No she won't"

"Now Blair I understand you're upset but this is your sister"

"I know it is my sister but she will not be staying with you I wouldn't be surprised if she was mad whenever she saw you mom you sent your daughter away and you admit she was a mistake she shouldn't be living with someone who is so careless like that so when she comes I am coming with you to the airport and she will be staying with me and Nate"

"Blair"

"I'm not asking for permission I'm telling you that's how it is going to be now she knows I exist right?"

"Yes ofcourse she's always wanted to meet you"

"Well Nate and I will welcome her with open arms and make sure you are not in her life since you seemed to be embarrassed by her and she will come to my wedding which means you won't"

"But Blair-"

"No mother now I am going to tell Nate this secret now when is she arriving"

"Tomorrow"

"Oh mother for god sake tomorrow? You decided to tell me now you are unbelievable"

"Blair I will not be ignored by both of my daughters"

"Well that's your fault now isn't it?" there was silence then her mother spoke

"Her flight arrives in the morning at 7:30"

"I'll be there with Nate" and with that she walked off.

Later…

Blair told Nate everything that happened at her mother's house

"Are you sure you want to take her in"

"Yes Nate I'm sure and plus the girl is seventeen she is Jenny and Eric's age so it won't be hard to talk to her and she can sleep in the guest bed and plus well I ;ve always wanted a younger sister"

"You are sure about this"

"Positive honey" Nate thought long and hard then he sighed

"When does her flight arrive" Blair squealed and hugged Nate

"7:30 tomorrow" Nate looked shocked

"Tomorrow? And your mom only told you now?"

"I know but we can meet her apparently she's always wanted to meet me so now she can live with us" Nate smiled

"So it's settled she'll live with us" Blair kissed him on the cheek and hugged him

"I love you"

"I love you too" he said forcing it out of him

"Honey how are we gonna tell everyone?" Blair said

"Well why don't we tell them tonight we can invite them for dinner and tell them"

"Okay I'll make some calls" Blair called Serena, Dan Eric, Jenny and Chuck and told them to come for dinner that evening
