Brad Pitt claims that he and Jennifer Aniston are still very good friends and that he just had to follow his heart to ensure he lived the life he dreamed of.

"Jen and I still maintain a deep friendship and have a lot of life together that isn’t erased in any way," the actor tells V magazine of the couple’s four-and-a-half year union, which ended in 2005.

"I don’t know how better to have handled [the split]. My view was, this was no one’s business in the end – at least in matters of the heart," he says. "The thing guiding me then was, you don’t know how many days you have, and you need life to be everything you need it to be." . . .

Adds Pitt, who now has four children with Angelina Jolie: "Those questions had to be answered before an attraction to Angie could be answered."

We’re curious about how Jennifer would describe their relationship. BFFs? Doubt it.

Oh…and here’s an Anatomy Lesson for Brad: That body part you followed out of your marriage and into Angelina Jolie? Clue - the heart is above the belt.

Got it? Good.

Entourage’s Adrian Grenier is doing his part to help America go green, one spoiled celebutard at a time. E! reports:

Paris, who sold her Hollywood Hills mansion last week for $4.25 million, is looking for a new residence in Beverly Hills. And her hottest accessory of the moment, Entourage star Adrian Grenier, is personally overseeing her selection, insiders exclusively tell E! online contributor Tina Dirmann.

"He’s helping her pick out a home she can easily convert in an environmentally friendly living space," Tina’s source reveals. "Adrian has really been teaching Paris a lot about what people can do to live their lives in a more ‘green-friendly’ way, because it’s a cause he’s very involved in. And so far, Paris is listening. She loves learning about the cause from Adrian and wants to become more involved."

Looks like this fledgling romance is more green than red hot! Especially considering a source close to the heiress reveals that while Paris and Adrian have shared a few kisses, "It’s really turned more into a friendship than a relationship. Paris thinks he is smart and respects how he sees celebrity. So, they’ve been hanging out a lot, but the two are more friends than boyfriend-girlfriend."

Adrian has helped Paris understand she can use her celebrity to promote any good cause if she wants to. "He told her, ‘You are the most photographed woman in the world! Think what you could do if you used that attention to bring light to a cause.’ "

And Paris responded. The starlet, who attended an event hosted by ForestEthics earlier this month with Grenier, is telling friends her next home will be as "electricity free" as possible. And she and Adrian are talking about collaborating on a new organization that teaches others how they can "go green" in their own homes.

We’re guessing that if Turtle arrived at her house to show her the ropes of going green, she’d plug his fat head into her environmentally unfriendly outlet. Face it Adrian, the only way Paris is going to go green is by smoking more of the herb.

Sienna Miller just came out denying anything more than friendship with Sean Combs. According to Rush & Malloy:

"I am in love with someone, but not Puff Daddy," she told ZeeNews.com. "He’s just a good friend. Anyway, he has a beautiful girlfriend."

They can’t be very "good friends" if she doesn’t use his name du jour.

Just in time, Diddy has released an official statement confirming the break-up with his Baby Mama.

Wonder if that dilutes Sienna’s statement. Will she rush to his side now that he’s actually single? Or will that make Puffy less interesting to her?

Rumors are flying that Tom Cruise is not happy with the Posh situation and that he and Katie Holmes are fighting about her close relationship with the British swizzle stick.

They say he’s not happy that Katie cut her hair into that cute bob, at the urging of Victoria Beckham. He has said that he prefers long hair.

Apparently he doesn’t like Katie’s new BFF guiding her wardrobe choices, either, and frankly who can blame him. Who wants their wife to morph into a PoshTart?

Tom, make up your mind! You either want a moldable young companion or you don’t.

When she allowed you to start calling her Kate and to provide an escort any time she left the house, you probably thought her receptiveness to direction was "cute" and "handy"…perhaps even "helpful to your career."

Getting all ticked because you’re not the only Svengali in town? Please. Live by the sword. Die by the sword, my friend.

The movers pick up the Beckham’s cleats and corsets Wednesday and they’ll soon be your neighbors. The British invasion has just begun.

Goody! Bet cutie-pie Suri can’t wait.
