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.
"Haven't Met You Yet"
So sweet! Michael Buble had his then girlfriend Luisana Lopilato (and a marching band!) appear in the video for his 2009 hit song "Haven't Met You Yet." The two lovebirds cuddled in bed and danced in a grocery store for the over-the-top video. The Canadian singer and Lopilato married in March 2011 and welcomed their first child, son Noah, in August 2013.
