Lady GaGa and Lily Allen: Pantsless Performing!

Lady GaGa, 22, and Lily Allen, 23, are two pop divas that realize that stardom is pants- optional.

Both singing sensations took to the stage recently in leotard/panty ensembles that symbolically flipped off winter.

GaGa took the stage at Dublin’s O2 arena last night in her usual vinyl corset, sunglasses and pink, sparkly panties.

And if you actually see GaGa with something on below the waist other than underwear, you know that she’s not wearing a shirt to make up for it.

Lily Allen dolled herself up in a frilly blue leotard, stockings and high heels to perform songs from her new album, It’s Not Me, It’s You at London’s G-A-Y Heaven nightclub on Saturday evening.

Who needs pants when you have mega stardom?
