Move over, Kim Kardashian and Kanye West. Another celebrity couple has decided to work together in a music video. John Mayer and Katy Perry express their affection in their first collaboration, “Who You Love.” The two stare lovingly at one another as Mayer sings lyrics such as "My girl, she ain't the one that I saw coming/And sometimes I don't know which way to go/And I tried to run before/But I'm not running anymore.” But is it too much?

In June, Mayer and Perry gave love a third try after breaking up in March. At that time, Mayer, 35, hinted at why he and Perry, 28, broke up for the second time, when he appeared on "Ellen.” Known for talking about his past loves, including Jennifer Aniston, Jessica Simpson and Taylor Swift, and their sex lives, Mayer was more private about his relationship with Perry, telling comedian Ellen DeGeneres, “It was a very private relationship going in, it was a private relationship during, and it’s a very private relationship still.

"I can understand asking the question based on some previous answers I’ve given, but I finally learned how to put the wall between one thing and another,” he continued. “Coupling is a tricky thing.”

It seems that third time's the charm for the couple, who ride on a mechanical bull in their new video, eerily similar to West and Kardashian riding a motorcycle together in West’s video “Bound 2.”

While it is a romantic idea to team up with your significant other for projects, it's not always advisable. Check out these celebrity couples who brought their real love life to the reel screen, with lackluster results.

Kim Kardashian and Kanye West


Kim Kardashian and Kanye West made themselves the butt of jokes when West released his video for the song “Bound 2,” which featured a nude Kardashian sitting on a motorcycle and embracing West as he drove. The video was spoofed by comedian Seth Rogan and actor James Franco. It was even blasted on South Park.

Jennifer Lopez and Ben Affleck


Jennifer Lopez and Ben Affleck, aka "Bennifer," were a huge media attraction when they dated in the early 2000s, but they should have avoided working together. Their 2003 film "Gigli" bombed at the box office, making just $7.3 million vs. its cost of $35 million.

Natalie Portman and Hayden Christensen


Natalie Portman and Hayden Christensen, co-stars in the 2000 film "Star Wars," failed to steam up the big screen. In fact, their chemistry was so nonexistent that they made it to No. 1 in a "worst screen chemistry" poll, published by screen advertisers Pearl & Dean.

Madonna and Guy Ritchie


Madonna and Guy Ritchie failed to recreate their real-life chemistry in their 2002 film "Swept Away." The movie, which was about a socialite getting stranded on a Mediterranean island with a sailor, drew tepid reviews from critics and bombed at the box office.
