Jennifer Lopez steals the show in skin-baring gown at 2017 NBC Upfront

Lights, camera, action!

The biggest stars on television hit the blue carpet at the NBCUniversal 2017 Upfront in New York City on Monday -- and they definitely outdid themselves this time around.

The week-long event, in which networks preview their programming for the upcoming TV season, kicked things off at NBC where a handful of the channels' biggest stars dressed to impress.

Some celebs opted for more casual looks, like Bethenny Frankel, who just announced that she's joining "Shark Tank" next season, and "This Is Us" star Mandy Moore. But then you have others who decided to go all out!

Jennifer Lopez, who has "Shades of Blue" and "World of Dance" with the network, made quite an entrance in a satin beige-pink gown that left little to the imagination. Lopez, 47, flashed major cleavage in the dramatic look, which was a total contrast from her sophisticated floral frock from the night before.

Newly-engaged couple John Cena and Nikki Bella couldn't help but pack on the PDA in front of the cameras, but it was Nikki's outfit that had heads turning. The brunette beauty took a cue from Lopez and rocked a strapless red frock that showed off her perfect pins and ample bust.

A handful of other NBC stars also hit the blue carpet, including Kristen Bell, Nicole Richie and Megyn Kelly. See all the arrivals in the slideshow above!
