Zac Efron knows how to win a woman's heart.

During an appearance on The Rachel Ray Show airing Monday, The Lucky One actor, 24, revealed the sweetest thing he's ever done in the name of love. "I'm a fan of small romantic gestures," Efron admits. "I've done things like write a romantic song for a girl or do a painting or something like that. Those are more up my alley, I think."

Efron -- who's rumored to be dating Mirror Mirror's Lily Collins, 22 -- says he's looking forward to taking some time off over the next few months.

"I usually like to travel during summer, so I'll probably go to Machu Picchu or something like that. I like to go backpacking and stuff," Efron says. "Why not try to go and get as much out of it when I can be alone and think?"

The actor adds: "It's very bare out there. It's fun. It's the best way. I'm pretty good about it -- usually I have my dad and my little brother with me. I hope they know what they're doing!"
