After spending a few days in London, the "Come and Get It" Pop star is now leaving the city looking more fantastic than ever with no signs of ever going into rehab just a month before last January 5. The 21-year-old singer and actress seemed like she is having a good time while spending time with her friends and One Direction's Niall Horan.

The recent news about her going into rehab because of substance and alcohol abuse was firmly denied by her representatives saying that it was all because of the emotional problems that the former Disney star has experienced with her former beau Justin Bieber. So now that the two are officially over, are they both moving on with their lives separately?

Bieber is busy partying in Atlanta and scouring properties for his possible move to the hip hop capital and seems to be recording new songs with his plans to enter the hip hop scene as "Bizzle." How about Selena? Well, she also partied with her friends in London and sparks are flying as she spent time with Niall Horan.

Niall Horan and Selena went out last Sunday night, February 16 after the latter arrived from Los Angeles. Pictures of the two together with some of their fans were posted and the two seemed to be having a good time together with their fans. The two have been linked in the past, however, some insiders believe that this is a ploy to win Bieber back.

Selena was also in high spirits on the night before leaving London as she had her girl's night out with friend Samantha Droke while sporting skimpy black shorts and a black midriff with a close fitted blazer and pink bubble gum stilettos, according to the Daily Mail. She even posted a photo of her holding a drink before dinner at the Sketch Restaurant with a caption, "Extra whip cream please! Dessert before dinner. Duh."

So now that she seems fine and dandy, many are asking if she is indeed fit and if there is a possible second trip to the rehab. Still the young Pop diva is looking hot and is keeping her mouth mum on the subject.
