Drew Barrymore and Justin Long have progressed in their relationship from hiding from the paps to showing up at events together, even holding hands and kissing on the red carpet. They also weren’t shy about making out in Drew’s car for the paps on her 33^rd birthday on Friday, where they celebrated with dinner at celeb hangout Mr. Chow and then headed over to the Chateau Marmot for a romantic evening together. They had a party for Drew with friends the night before. These two met last summer on the set of Drew’s upcoming romantic comedy He’s Just Not That Into You , in which Long stars, and took pains to keep their relationship quiet until January.

Drew is featured looking glam on the cover of the March issue of Vogue, and she talks a little about her relationship with Long in the accompanying interview. The twice-divorced Drew said that she feels immature when it comes to her relationships, but gushed about how happy she is with Justin. Somehow Vogue was talking to Justin too, because People.com reports that he sings her praises in that article. They also say that Drew knew Justin for seven years before their relationship became more than friends:

Tracking the relationship between the actress-producer and the “Mac” in the Apple computer commercials, the March issue of Vogue, reports that the two knew each other for seven years before becoming serious.

Asked for his immediate reaction to what he thinks of when it comes to Barrymore, Long – who helped Drew celebrate her 33rd birthday this month – responds, “Beauty and light, and she shines it on everybody who comes into contact with her.”

As for her reaction to Long, a perennially smiling Barrymore says, “My cheeks hurt, I’m so happy.” Adds Long, 29: “She makes my cheeks hurt, too.”

It wasn’t always so. While Barrymore considers herself secure in terms of dealing with her profession and her friendships, as far up-close-and-personal relationships are concerned, “for some reason, I have not grown up to the speed I am elsewhere,” she says.

It’s hard to find the right person for you, and although it does seem strange that Drew’s marriages lasted less than six months combined it seems like the mistake she made was marrying those particular guys, not being with them. She was with Strokes drummer Fabrizio Moretti for years, and then was said to be dating Sophia Coppola’s ex Spike Jonze last year before hooking up with Long. She shouldn’t put herself down by saying she’s somehow less “grown up” because her relationships didn’t work out. You live and learn and sometimes the timing is wrong or you realize it’s not the right person for you. Just don’t get married again until you have a good track record with someone and are sure about it.

In January, 2007 Drew told Harper’s Bazaar about how great her relationship was with Fabrizio Moretti, saying “You need to reinvent your relationship if you want to continue being together. Right now I’m in a phase of ‘I’m not even your girlfriend. I’m your best friend who is madly in love with you.’ I’m really interested in watching him right now. The longest I’ve ever been with someone was like two to three years, so I’m in uncharted waters.” They were reported to have broken up by the time the issue was out. Maybe she’s right that she needs to be careful in that department.

29 year-old Long is best known as the Mac guy in the “Get a Mac” commercials, and stars as the voice of Alvin in the Alvin and The Chipmunks movie. He was educated at Vassar and hails from Fairfield, CT. People reports that Drew’s friends approve of him and say he’s a great guy.
