Selena Gomez hotel justin bieber montage beverly hills singer

It may be February, but Selena Gomez is already busting out her summer clothes!

On Friday Selena went to a meeting at a hotel in Beverly Hills, and the 21-year-old pop starlet showed off her toned tummy in a skintight crop top and flowy pants. Selena also gave us a peek at her black lacy bra underneath ... whoops!

While she looks great, she isn't exactly the healthiest eater, so we've always been curious as to how she maintains such a trim figure. Yesterday Justin Bieber's former flame stopped by Taco Bell, on Tuesday she Instagrammed a photo of herself chowing down on an egg McMuffin at 7am, and the day before that she posted a pic of herself slurping down a beverage covered with whipped cream. She also frequents Jack in the Box, loves her slurpies, and though she's faced concerns over her dietary habits before, she doesn't seem too worried about changing her ways!

Back in June of 2011 when she was hospitalized after collapsing following her appearance on The Tonight Show, she told Texas DJ Kidd Kraddick that malnutrition was one of the reasons for her collapse. "I do eat. The problem is I don't eat right," she said. "I love everything that's possibly not good for me I was a stubborn kid, so I got to eat whatever I wanted. I have to have creamed spinach or cheese on my broccoli. I have to have something that makes it not healthy."

Lucky girl ... she must have a really high metabolism!
