Dangerous curves ahead!

Jennifer Lopez but her bod on display in a tight knit top and pencil skirt on her way in to tape Monday night's Jimmy Kimmel Live. Fans went wild as the diva made her way backstage in a blush pink, monochromatic look, with mesh pumps, accessorized with a tan bag.

Lopez is gearing up for the Jan 7 premiere of cop drama Shades of Blue, in which she stars as a member of Brooklyn's finest who's tapped by the FBI to be an informant. It's a weekly, hour-long drama that will kick her schedule and her life in the ass, but she wanted to do it because it reflects what's going on in "society and what's happening today." She executive produces and her co-star is Ray Liotta, of Goodfellas fame. Sounds like it could be a winner!

Meanwhile, the 47-year--old opened up about her on-again relationship with Casper Smart while making a stop at the Ellen DeGeneres Show, which is set to air on Tuesday. The sultry singer revealed that she spent New Year's with her younger man, telling DeGeneres, "We were down in Miami together for New Years he was working I didn’t have to work I had literally two days off. We just we were hanging out."

Lope, who has been married three times before, also insisted she won't be walking down the aisle with Smart. When the talk show host asked her about any plans to tie the knot, the triple threat said, "No wedding. There’s no wedding!"

We guess we will have to wait and see!
