How do you score points with your daughters? All Martin Lawrence had to do was tell them his co-star in College Road Trip was Raven-Symone.

“My girls are huge fans,” he told me. “We all used to sit down together and watch her show, That’s So Raven. So naturally, I had to take them to the set to meet her, and that made me a cool dad.”

Lawrence has high praise for Raven, who first grabbed hearts of viewers as a sassy three-year-old on The Cosby Show.

“She grew up in the business, but she has a head on her shoulders,” he says. “She reminds me of Lucille Ball. You can tell that she’s been a big fan of Lucy.”

Raven holds her own with Martin in College Road Trip as he insists on tagging along when she and a group of friends go on an orientation visit to Georgetown University.

Playing a dad who can’t let his kid go off to college alone was a lesson for Lawrence.

He says, “I began to understand I’ve got to give my daughters some space to grow up.”

Lawrence skipped college in real-life to head for Hollywood, but I found out he did a road trip to his old high school.

“I went back to visit Ms. Henderson, who we used to call ‘Froggy,’” he says. “When I was a student, she gave me a card advertising a club, the D.C. Comedy Café, in Washington, and said, ‘Martin, stop making people laugh and disrupting the class all the time and try it in front of an audience. If you ever make it, you can buy me a car.’ Flash ahead to my success, and I did get her a car.”
