The Shades of Blue star wasn't the only one showing off her backside, however. On Monday, host Jenna Dewan Tatum flaunted her figure in a black-and-white striped crop top, black pants and strappy stilettos.

"Super serious backstage as always," she joked.

The girls looked equally gorgeous on Wednesday, posing with judges Derek Hough and Ne-Yo on the red carpet during a photo op for World of Dance at the NBCUniversal lot in Los Angeles.

Dewan wore a classy black-and-white dress, which featured a thigh-high slit, while Lopez opted for an all-white look. Hough kept it casual in a burgundy jacket, button-up dress shirt and jeans, while Ne-Yo suited up in a silk tuxedo.
