Showing off their love -- on and off screen! Some Hollywood A-list couples don't mind taking their work home. Here's to Beyonce and Jay Z, John Mayer and Katy, and other celebrity couples who've appeared in each other's music videos.
"Who You Love"
Riding into the sunset! John Mayer and girlfriend Katy Perry rode mechanical bulls in the music video "Who You Love" for their duet in December 2013. After performing the love song together during Mayer's Paradise Valley tour at the Barclays Center in Brooklyn, Perry went on to say that their video was more "authentic" than Kimye's "Bound 2" during an appearance on the Ellen DeGeneres Show. The two began dating in summer 2012, briefly split in August 2012, and got back together one month later.
