It's like she's sexing it up to get his attention!

Selena Gomez looked smoking hot in bell bottoms and a crop top as she caught a flight out of LAX today, and given the spring she has in her step, we think those rumors that Justin Bieber canceled appearances to dedicate his time to winning her back are true!

JB pulled the plug on going on The Late Show with Stephen Colbert and then backed out of a scheduled taped performance for the Thanksgiving Day Parade in NYC, citing his inability to make it to the Big Apple.

Perhaps he couldn't make it because he already planned on spending Thanksgiving with Selena? Or maybe he couldn't handle the heartbreak of learning that the "Come & Get It" songstress has been spotted spending time with One Direction stud Niall Horan? The brunette beauty and the boybander dined with her parents at Nobu in Malibu on Monday, and even though sources say they are strictly friends, it can't make her Canadian sensation ex feel too comfortable.

If we were betting gals, we would put our money on the fact she's jetting off to spend the holiday with The Biebs!
