Jennifer Lopez is how old? Showing off her amazing body on the Ellen DeGeneres Show, J.Lo looked sexier than ever.

While Lopez dished on her relationship with Alex Rodriguez on today’s show, we couldn’t stop staring at her body. At one point, she and Derek Hough did a dance-off. And Lopez’s legs looked amazing in an itty, bitty, thigh-high mini. The mini was so short that she had to pull it down at one point!

Clad in some incredible heels, Lopez said she didn’t have her dancing shoes on. But her gorgeous gams were on full display throughout the dance-off. She did everything from a belly dance to the Moonwalk.

DeGeneres told Lopez she looked “fantastic.” She wasn’t feeling well the last few times she was on the show, but she was 100-percent now. And she looked it.

In the past, Lopez has opened up about her diet and exercise regime and how she got her fabulous legs. She works with trainer Tracy Anderson. One move she does is the Fire Hydrant to Arabesque with a three-pound weight. She also does the Push-Up with Leg Kick with the weight.

Lopez also opened up about her relationship with Alex Rodriguez. “He’s a great guy,” Lopez said. She and A-Rod saw each other while Lopez was eating lunch. She had a salad and soup. He passed her and she tapped him on the shoulder to say hi later. “And then that was it,” she said.

They realized they both lived in L.A. and he said they should hang out. He had her number from “years ago.” He texted her, they went to dinner, and the rest is history. They didn’t have a “sleepover” on the first date though. “So maybe you two will have children?” DeGeneres asked. They were just having a good time for now. Then someone in a Yankees uniform jumped out and surprised J.Lo.
