Alex Rodriguez Just Shared A Hilarious BTS Super Bowl Video And J.Lo's Abs Are The Clear Star

Jennifer Lopez and Shakira's Super Bowl Halftime Show was instantly iconic. There were so many memorable moments, like J.Lo singing with her daughter Emme and Shakira's awe-inspiring abs .

But J.Lo's fianc, Alex Rodriguez, just revealed a few more behind-the-scenes moments you may have missed on Instagram. Did you know he was a backup singer at the show? He was, and he has the video receipts to prove it.

A-Rod wrote in the caption: "When Jen told me I could be a background singer, man, she wasnt kidding. Waaaay in the background. #CanYouFindMe #TallGuyWithShadesOn #jlosuperbowlchallenge."

A-Rod may be waaaay in the background, but J.Lo and her super toned abs are front and center, leading the whole group through some "On the Floor" choreo. Peep the video and see for yourself.

J.Lo showed off basically every inch of her toned bod in the Halftime Show, but her six pack stayed under coveruntil now. So, how does the superstar maintain her strong abs?

J.Los trainer told that the Hustlers star's abs workout consists of a set of 50 hanging abs raises followed by 50 rope crunches and 50 incline sit ups with a 45-pound plate. That's just the start. Then, she does another set of 35 each, followed by a third set of 21 each. Oh, and she doesnt take breaks.

A busy schedule like prepping for the Super Bowl or touring doesn't get in the way of her sweat sessions, either. On her recent "It's My Party" tour, she made a stop at the Dallas Cowboys' training gym for a workout with A-Rod. And the celeb couple has also done fasted cardio together , plus a 10-day workout challenge they posted on YouTube.
