I think I was like 17 or 18, like the love of my life, like my boyfriend who I was obsessed with in love, my first love, left me on Valentine's Day and moved back home. He just left -- like never said anything. Who leaves on Valentine's Day when you have a girlfriend that you're supposedly in love with? I get it. it was young love, but it really, really sucked, and I think it ruined every Valentine's Day from there on out."Tate Donovan: "I spent a ridiculous amount of money on a pair of Tiffany diamond stud earrings for a girlfriend -- it wasn't Jen Aniston!

I was just, like, I can't win."See photos from the "Valentine's Day" movie premiereHayden Panettiere: "I went through a bad breakup and spent the day at a restaurant called Birds, where they had an anti-Valentine's Day party.

I was really bummed. I put hours of work into it and he showed up drunk."Chad Michael Murray: "A guy friend and I went to California Pizza Kitchen, and a group of pretty girls came over to us and said, 'You guys are gay, right?' I wound up really lonely."Michelle Trachtenberg: "I once dated a guy who was like, 'Holy s**t, I just made out with Harriet the Spy!' And that's messed up. Don't say that.
