Jacinda's already making waves as Zach Braff's GF in The Last Kiss. But starting this Friday, you can also catch her smooching funnyman and Napoleon Dynamite star Jon Heder in School For Scoundrels. In the movie, Jon snags a date with Jacinda after taking a course on how to get girls. Bummed that your school doesn't offer a class on how to get guys? No worries. That's why we have Ms. Barrett to teach us.

1. Be independent.

"I was really heavily into sports because I enjoyed them so much, and it helped my focus. It kept me busy, and probably kept me from getting into trouble sometimes, you know?" So what sport did Jacinda play? "I played Net Ball, which you guys don't really play in America. It's sort of like basketball, but the hoop doesn't have a backboard on the back. I played that all the time, and did gymnastics, too. And I was sort of a late developer -- I don't think I had a real BF until I was 17!"

2. Don't Try Too Hard.

According to Jacinda, she's never done anything crazy to get a guy. "I don't think it works that way," she admits. "I don't think that if you do some crazy moves, that you win someone that way. I think people connect based on who they are." So how did Jacinda meet her soul mate, fellow actor Gabriel Macht? Randomly, at an audition! She says they only exchanged one sentence, but were able to meet up later for a blind date, through the help of a mutual friend.

3. Lay The Smack Down.

"Don't accept negative treatment from someone ever, ever, ever," says Jacinda. " I don't think any woman should have to put themselves in that situation. You want someone who treats you with kindness and dignity -- someone you feel like you can be yourself around, and someone who feels they can be themselves around you."

4. Be Yourself.

In School For Scoundrels, Jon Heder does some pretty crazy things to get Jacinda's attention. In real life, though, Jacinda thinks you should let things happen naturally. "Just be yourself. I don't have any tips -- there's no rhyme or reason," she says. "But I think it's all about keeping your integrity because people are attracted to that. The most important thing is that someone treats you with respect and accepts you for who you are. If someone asks you to be different, or asks you to change, that should be a red flag."
