Jennifer Lopez's sexy dancing with beau Casper Smart in her new music video "didn't feel forced."

The 42-year-old performer and her 24-year-old dancer beau have been dating each other for a few months following Jennifer's split from estranged husband Marc Anthony.

In several scenes of Jennifer's new Dance Again video, which debuted on American Idol Thursday night, the couple are scantily clad and erotically gyrate with one another.

Jennifer felt comfortable with the sizzling routines she and Casper performed.

"It was just a very natural thing for us to do together," Jennifer told Extra in a joint interview with Casper. "Everything that the song is saying -- where I'm at -- it was just very natural. It didn't feel forced."

Casper confesses that the lovebirds did butt heads on set at times.

"Me and Jen work well together. The only thing in rehearsals... we had a couple grouchy moments 'cause we both were fasting for the video to get in great shape," he explained.

Now that the video has been released, Jennifer and Casper are focusing on Easter celebrations.

The couple visited the Easter bunny this week with Jennifer's four-year-old twins Max and Emme and will continue to keep holiday celebrations low-key.

"I don't know [what we'll do this year]," Jennifer said. "Usually my family comes over, we cook, we do a little Easter egg hunt with the kids, get them baskets."
