Even the Terminator is a sucker for romance.
Arnold Schwarzenegger, who's been married to NBC's Maria Shriver for 15 years, says Valentine's Day still pierces his heart. He says it's the little things that makes his relationship work.
" I bring coffee," he says. "Every morning I bring coffee to my wife and serve her and do all kinds of things like that.
"I can't even tell my friends that because they would immediately say, 'You traitor! You're selling out. How can you do that? You make us look bad!'"
Schwarzenegger, back to macho action roles in the recently released Collateral Damage, says he doesn't have to live up to his image when he's home. "Most of the time I don't admit how much I'm selling out as a man," he says. "But my wife could tell you that I'm into the whole romantic thing … You know, flowers, and the gifts and taking her on trips and all those kind of things." Stiller: Diapers on the Brain
Ben Stiller greets Valentine's Day as a first-time father-to-be. He married his Zoolander co-star Christine Taylor in 2000, and they're expecting a son.
The star of Meet the Parents and There's Something About Mary says real love is nothing like the light-hearted romantic comedies he's famous for.
"I don't think you can be romantic just to be romantic," Stiller says. "Y'know, romance comes out of real feelings for somebody, so I think you just kind of go with … what you're feeling, and if it moves you to do something that maybe sometimes feels a little romantic." Carrey: ‘Romeo’s Dangerous’
Show business can be hard on a relationship. Jim Carrey, who says he's currently unattached, says love has brought him to his knees many times. He jokes that being a Romeo isn't what it used to be.
"It's a weird thing these days. You can't be romantic because you're a romantic if you're a stalker," he says. "You don't show up under the window anymore, you know what I mean? It's like [people will start saying] 'Romeo's dangerous.'"
Carrey's been married twice, to actresses Melissa Womer and Lauren Holly. He was dating Renee Zellweger, whom he met during the filming of Me, Myself & Irene, but the relationship reportedly ended in the late fall of 2000.
Still, he says he isn't giving up. "I don't know what the hell's going on there," he says. "But I do know that I totally believe in it." Crowe: ‘I’m An Expert in Unrequited Love’
Russell Crowe, who's been regarded as Hollywood's leading Casanova, admits he still has a soft spot. With his rock band, 30 Odd Foot of Grunts, Crowe has written numerous love songs, and recently admitted that he was in fact in love with his Proof of Life co-star, Meg Ryan. "My love songs are usually about unrequited love, which I, for some reason, am expert in," he says. "When I'm writing a love song, it's always from the point of view of loss."
