Jennifer Lopez, Casper Smart & Other Sexy Celebrity Couples in Music Videos (PHOTOS)
Jennifer Lopez knows how to mix work with pleasure. The 42-year-old pop star released the sultry video for her new single Dance Again, which features her much-younger boyfriend, 24-year-old Casper Smart. The two get hot and heavy in the video -- but this isn't the first time JLo has had a boyfriend star alongside her. Bennifer, anyone?
Back in 2001, the sexy pop star packed on the PDA with then-boyfriend Ben Affleck in her steamy, butt-touching video for "Jenny from the Block."
Instead of casting a random co-star, many singers opt to get down with their significant others for their music videos. From Britney Spears and Jason Trawick to Beyonce and Jay-Z, click through the gallery to see other Hollywood couples who've filmed videos together.
