Oops! Selena Gomez suffered an embarrassing wardrobe malfunction while performing at the 103.3 AMP Radio Birthday Bash in Boston on Sunday, June 30. She wore a yellow  dress and was dancing feverishly when a gust of wind came along and Sel showed a little leg... And perhaps something more, thanks to the slits in the skirt.

How much and what the singer showed is a matter of conjecture and perception.

Sources are reporting that Sel flashed Spanx, which as most of you know are shapewear garments that are meant to smooth, restrict bulges and avoid any sort of pantylines. However, in some images, it doesn't look like underwear. It looks like... skin. That would mean that Gomez went commando while performing.

So either she wore flesh-colored Spanx… Or nothing at all. It's really not clear. All we know is that she was likely not counting on flashing anyone, sans undies or with Spanx.

Sel was filmed performing 'Slow Down' and you can see her struggling with her dress, trying to hold it down and smooth it and as gusts of wind come her way.

She also performed 'Love You Like a Love Song' and can be seen fidgeting with the slits.
