This is random: Avril Lavigne is set to marry Nickelback lead singer Chad Kroeger after a six month relationship. The pair confirmed their engagement on Tuesday night and Lavigne showed off her 14-carat engagement ring on Wednesday.
"A romantic relationship blossomed as they spent time writing together," a Lavigne friend told People. "He makes her so happy," a family source tells People. "Both of their families could not be more excited."
Their relationship might seem weird, but they're hardly the first random celebrity couple in Hollywood.
Jean Claude van Damme and Kylie Minogue
"Expendables 2" actor Jean Claude van Damme surprised fans in mid-August when he admitted to bedding Australian pop star Kylie Minogue while filming the 1994 stinker "Street Fighter."
"Yes. OK. Yes, yes, yes. It happened," he finally admitted after trying to deny it. "I was in Thailand, we had an affair. Sweet kiss, beautiful love-making."
"…She's so beautiful, and she was there in front of me every day with a beautiful smile, simpatico, so charming, she wasn't acting like a big star," he continued. "I knew Thailand very well, so I showed her my Thailand. She's a great lady."
Diane Keaton and Keanu Reeves
Rumor has it veteran actress Diane Keaton and Keanu Reeves hooked up while filming "Something's Gotta Give" back in 2005. Nothing was ever confirmed, but she did show up at his Hollywood Walk of Fame ceremony.
Get it, girl.
Michelle Williams and Jeremy Jackson
Actress Michelle Williams might be dating adorable funny guy Jason Segel now, but she did have a love of the bad boys back in the day. One of those bad boy conquests? Former "Baywatch" star Jeremy Jackson. He told the New York Daily News that they dated for two years and that was both his first real love and sexual experience.
"I was learning the ropes, man," he told the newspaper. "If you want to make an omelet, you've got to break some eggs right?"
Lance Armstrong and Ashley Olsen
Ashley Olsen apparently has a thing for older guys: She's currently dating French businessman Olivier Sarkozy, but she also dated cyclist Lance Armstrong back in 2007. Or, maybe more like hooked up.
"They came together with a group of friends," a source told the New York Post of the pair's rendezvous at the Gramercy Park Hotel bar. "Ashley drank red wine, sat on his lap and they were making out all night. They left together around 2 a.m."
Do you think Avril Lavigne and Chad Kroeger will make it work?
