Although the couple is rarely photographed together, their relationship appears to be heating up. According to People magazine, Zellweger celebrated Christmas with Cooper's parents in Los Angeles. The tabloids are also reporting that the couple recently purchased a California mansion.
Taylor Swift and Taylor Lautner:
It could have been so perfect but the tale of the two Taylors has no Hollywood ending, at least not in real life.
In "Valentine's Day," Lautner plays Willy, a track star and the boyfriend of Felicia, played by Swift. On screen, Lautner gives Swift a big French kiss. Off screen, romance between the two flickered for three months before it fizzled in December.
Friends of Swift told US Weekly that after a series of wholesome dates, including one over frozen yogurt alongside Swift's mom, the sparks just weren't there. "It wasn't really developing into anything, and wasn't going to, so they decided they were better as friends," the source told US. "There was no chemistry."
It also appears that Swift, 20, was just not that into Lautner, 17, as he was into her. "He liked her more than she liked him," the US source said. "He went everywhere he could to see her, but she didn't travel much to see him."
Or maybe Swift was still guarding her heart after her 2008 breakup with Joe Jonas, which she has said took place in a 27-second phone call and inspired one of the songs on her hit album "Fearless." She told Ryan Seascrest that Jonas was the only guy to really break her heart.
In "Valentine's Day," Kutcher plays a shy florist who wakes up early to propose to his girlfriend, played by Jessica Alba, who seems more interested in her cell phone than marriage.
In real life, Kutcher, 32, is happily married to an older woman, 47-year-old Demi Moore. He wasn't always interested in older women, though.
Before Moore, Kutcher dated January Jones, who recently told GQ magazine that Kutcher was not supportive of her acting. "He was like, I don't think you're going to be good at this. So -- f*** you! He only has nice things to say now. If anything, I should thank him. Because the minute you tell me I can't do something, that's when I'm most motivated."
Moore also dated actresses Ashley Scott, Monet Mazur and Brittany Murphy. When Murphy died recently, Kutcher Tweeted, "2day the world lost a little piece of sunshine. .. see you on the other side kid."
After his breakup with Murphy in early 2003, Kutcher began seeing Moore. Although initially considered a fluke, their relationship has stood the test of time. They were married Sept. 24, 2005, in front of 100 close friends and family, including Moore's ex, Bruce Willis.
As a young starlet who was ranked No. 1 on Maxim's Hot 100 list, Alba, now 28, was linked to several men, including actors Wilmer Valderrama, Mark Wahlberg, Scott Caan and athlete Derek Jeter.
But she came from a surprisingly conservative Christian background. At age 20, when she became engaged with her "Dark Angel" co-star Michael Weatherly, 12 years her senior, her parents were not happy. After the couple ended their relationship in 2003, Alba later spoke out about it: "I don't know [why I got engaged]. I was a virgin. He was 12 years older than me. I thought he knew better."
