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.
"Where You Are"
Newlyweds no more. Jessica Simpson and Nick Lachey -- who appeared on MTV's Newlyweds: Nick & Jessica in 2003 -- both appeared in Simpson's "Where You Are" music video in 2000 off her debut album Sweet Kisses. (Simpson also appeared in Lachey's 98 Degrees video "My Everything" in 2000.) The pair tied the knot in October 2002 and divorced in June 2006.
