On American Idol this week Jennifer Lopez will debut her new music video for "Dance Again," which just happens to feature her boyfriend Casper Smart. We hate to question the logic of a woman who's reminded us that she's still "Jenny from the Block," while wearing nothing but a bikini bottom and a fur jacket, but if anyone should see the problem here, it's J.Lo. She appeared in multiple videos with her ex Marc Anthony and infamously put Ben Affleck in a video during the height of the "Bennifer" craze. Perhaps Lopez hopes to get back at her exes by showing off her hot new boyfriend, but in a few years she'll cringe every time she sees "Dance Again" on MTV on YouTube.
Is co-starring in a music video always a relationship jinx? Let's take a look at the evidence. After all, diamond engagement rings can be returned, but the Internet is forever.
Britney Spears & Kevin Federline in "My Prerogative"
"My Prerogative" is a delightfully ridiculous video, and it's only helped by the presence of Britney Spears' then-fiancé Kevin Federline. In the clip Spears marries K-Fed during what appears to be a rave-themed wedding. Though their real-life union didn't last, Spears is still a fan of music video PDA. Last year she put new fiancé Jason Trawick in her "Criminal" video. Hopefully she won't have to pull a Justin Timberlake and act out their relationship problems on video, "Cry Me A River"-style.
Michael Jackson & Lisa Marie Presley in "You Are Not Alone"
Though Michael Jackson and Lisa Marie Presley make out in the nude in this video, amazingly, it isn't the most embarrassing moment of their relationship to be caught on camera. Note: Don't proclaim, "Just think, nobody thought this would last" in front of a TV audience of 250 million unless you're sure you won't be divorced within two years.
Adam Levine & Anne Vyalitsyna in "Never Gonna Leave This Bed"
Though the couple just announced that their relationship is over, they'll always have this video of themselves cuddling in bed for three and a half minutes to remember it by.
Carrie Underwood & Mike Fisher in "Mama's Song"
Making a music video hasn't spelled doom for every couple. Carrie Underwood and Mike Fisher tied the knot in 2010 and their relationship has been going strong ever since. That's good, because this tearjerker video about how Fisher "treats your little girl like a real man should" is going to be really awkward if they break up.
Beyonce and Jay-Z in "Crazy in Love"
Beyonce and Jay-Z have always been protective of their relationship, and they hadn't even confirmed that they were dating when "Crazy in Love" was released in 2003. Of course, the world now knows that they've married and welcomed a baby girl, but if they'd split the world would only remember this as a great collaboration between two artists. Ironically, their decision to make a music video together wasn't crazy at all.
