David Foster is not a happy guy.

In fact, the world-famous Canadian-born record producer should be in anger-management classes, his stepson Brody Tanner says.

"Dave's crazy -- he's just an angry person. We have 10 bedrooms and he's trying to kick me out of the house," says the 21-year-old drummer, actor and model from California.

"He said ... I had to pay $4,000 a month to live here, so I decided to make money in ways that suit my lifestyle. It turned into an all-out war."

That is the premise behind Fox's new show The Princes of Malibu.

"Basically, he (Foster) does something bad to me and I do something bad to him," says Brody.

The unscripted series actually started as a documentary on Malibu life, he explains.

"My best friend Spencer (Pratt)... asked if he could film me. At the time I had dropped out of college and my stepdad was always yelling at me -- we thought it was really funny."

Believing they had something potentially very entertaining, the boys pitched the idea of a reality show about Foster and his two stepsons, Brody and Brandon Tanner, to Fox.

"The show was created for pure entertainment -- nothing else. It's about kids having fun and making the best of their lives," says Brody.

Set in ritzy, sun-drenched California, The Princes of Malibu uncovers the humorous situations that arise as Brandon and Brody live the high-life while trying to co-exist with their irate father and doting mother Linda Thompson.

It's about a family that has everything -- a 22-acre compound by the sea, fabulous cars, bank accounts to dream of and looks to die for.

But, though their luxuries are extraordinary, they have the same types of problems as any other blended family.

Foster wants his stepsons to contribute to the household, get jobs or get out. Their mother, however, doesn't mind her boys taking the time to "find their way" while enjoying the fruits of Foster's labours.

"No lines are scripted, but there are events at the centre of each episode," says Brody.

During the first show, Foster and his wife return home from vacation a day early to find Brody's 21st birthday party overrunning their Malibu estate.

The raging pool party is the last straw for Foster, who decides to finally put his foot down.

"It's a real family, a real house and real situations, but they are exaggerated.

"We had to add the bells and whistles to make it a good show, but the problem is very real," says 23-year-old Brandon, whose band Big Dume will have its music featured on the show.

"We are creative kids -- this TV show enabled us to do all the things we wanted to do. Music for me is why I did it."

Introducing millions of Americans to his band may have been Brandon's initial reason for signing up, but, he says, the experience ended up being one of the best of his life.

"We set up a drive-in movie theatre (on the front lawn) and did crazy things like that.

"These are things Brody and I had talked about doing for a long time and we finally got the chance," says Brandon.

"Hopefully people will get a kick out of it and it will make them smile."

The Princes of Malibu, which features several celebrity cameos, including Celine Dion, Brooke Shields and David Hasselhoff, airs tonight on Fox and Global at 9:30 p.m.
