Jennifer Lopez definitely pushed the boundaries recently set by the Grammy's "no skin" rule during last night's ceremony.

The singer/actress opted for a little flash of the leg at the Grammy Awards, letting it all hang out like Angelina Jolie at last year's Oscars.

This wasn't, of course, Lopez's first outfit to bare skin. No one can forget that back in 2000, she wore the now infamous green Versace dress that left little to the imagination except the unmentionables from her neck down to just below her belly button. Lopez still has the dress, which she reportedly told Harper's Bazaar recently.

Her option at this year's Grammys was much more modest, an Anthony Vaccarello black gown that bared her arm and leg only. Given CBS' warning about not revealing parts of the body like "under curves of the buttocks" or "bare sides or under curvature of the breasts," it was bold in terms of the amount of skin revealed, which showed off her leg straight up to the hip.

She also gave a nod on the red carpet yesterday to Angelina Jolie's now famous leg stance at the 2012 Oscars.

"They didn't say anything about leg!" Lopez reportedly told E! News. "I thought I was being such a good girl! A little shoulder, a little leg."

Jolie's leg caused quite a stir at last year's Oscars ceremony. Her black velvet gown, designed by Atelier Versace, also revealed her bare arm and leg straight up through the hip. It's uncertain what number the Oscar-winner will decide to wear at this year's awards ceremony, which will air on ABC on Feb. 24.

So who did the single leg better, J-Lo at the Grammys or Angelina at the Oscars? Give us your take and decide who had a "leg up" on the competition!
