A few weeks ago, during an appearance on England's popular "The Graham Norton Show," pop sensation Lady Gaga announced that she's single, saying, "I don't have a boyfriend and I haven't been on any dates recently." (Ironically, she chose to wear a wedding dress to make her statement.)
Her split from Luc Carl, a New York City based bartender and musician whom Gaga had been dating for on and off for a few years, seems to have been a painful one for the two of them. Lady Gaga had famously cited Carl as an inspiration for her music, but with her success came frequent travel and work, which might have put a strain on her relationship.
Hayden Panettiere and Wladimir Klitschko
These two shared a 15-inch height difference, but the vertical challenge didn't stop them from dating. But the lateral distance between them ended their relationship, as heavyweight boxing champ Klitschko told People magazine. "We had a great time together, but it's not that easy to manage a relationship between two continents," he said.
Actress Panettiere told People, "Even though we've decided splitting up is best for both of us, we have an amazing amount of love and respect for each other and remain very close friends."
Leonardo DiCaprio and Bar Rafaeli
The Hollywood heavyweight and world-class model made a gorgeous duo but, alas, it was not meant to be. Rafaeli, 25, doesn't appear too upset about her recent split from DiCaprio, as she was photographed frolicking on yachts at the Cannes Film Festival during the day and partying on the town at night.
DiCaprio doesn't seem to be losing sleep over the breakup either. He has been spotted in Italy with "Gossip Girl" star Blake Lively.
Joe Jonas and Ashley Greene
Tons of tweens celebrated Jonas and Green. Pictured as the perennially sweet boyfriend, the "Jonas Brothers" crooner seemed to be the perfect guy for "Twilight" star Greene, until their relationship ended. They reportedly broke up close to Greene's 24th birthday. But the starlet has been seen out and about on the beaches and red carpets of L.A. while Jonas seems to be coping just fine by bonding with his bulldog, Winston.
Bradley Cooper and Renee Zellweger
These two box office darlings dated less than two years, but from the first time they were linked together, their relationship was more of an undercover romance than front-page tabloid fodder. Rumors flew that Zellweger, 42, had back burnered her career to be a good girlfriend to Cooper, 36, who embraced leading-man status earlier this year with "Limitless."
By all accounts, however, their romance seems to have simply petered out, with Cooper enjoying a lifestyle that conflicted with the low profile that Zellweger preferred. He seems to have moved on to a flashier star: Olivia Wilde of "House" and the film "Tron: Legacy."
