"I don't know if it was Britney's or her roommates, but it belonged to somebody! And whoever that somebody is, she is pregnant."

The -housekeeper also reveals that Spears is a nice gal, but dirty.

"I was able to meet Britney a few times while she was in rehab. She is a really sweet girl. You could tell just by looking at her room that she loved her children and their father..she had photos of them on her nightstand. A lot of the staff talked about how she was having problems adjusting to rehab but I was never around her that much to see it."

"I have seen worse. But yeah, she did keep things messy. Mostly, it was clothes laying all over the place."

Last month, News of the World reported that Britney wanted another baby with Kevin Federline

A source claimed that Britney's time in rehab had given her the time to reconsider her separation from Kevin and was ready her to give their marriage another go: “Kevin has been a real tower of strength for her and she has finally decided to give their marriage another shot.�?

“She thought things were over between her and Kevin after his wild partying and gambling. She felt he had deserted her and left her to bring up their two children on her own. She never even dreamed she would take him back.�?

“But Kevin’s like a different man now. He’s never been so caring before, and is really worried about Britney. He’s been Britney’s rock during her difficult time, and she wants to give him another chance.�?

"She just wants to be with him again, and thinks having another baby will seal their marriage.�?
