Ben Stiller and Christine Taylor's children are distinctly unimpressed by Justin Bieber's cameo in their film star parents' latest movie, Zoolander No 2.

In the sequel to 2001's Zoolander, the Canadian pop star meets his end after a night-time chase through the streets of Rome, amid a spate of celebrity killings.

However, the Hollywood couple's children - Ella, 13, and Quinlin, 10 - were hardly excited.

Speaking at a "fashionable screening" of the film in London's Leicester Square, Taylor explained: "Our daughter, who is almost 14 - of all of the 14-year-olds on the planet, she is the one child who is like: 'Dad, I get it, everyone loves Justin Bieber, but I'm not one of them.'"

However, another celebrity cameo earned the film's star and co-writer Stiller some respect from his daughter.

Taylor, who plays Derek Zoolander's on-screen love Matilda Jeffries, said: "Benedict? Let's not get started. Ella, our daughter, is obsessed with Sherlock, obsessed with Benedict, so Ben's street cred rose in huge amounts the minute that she found out that Benedict was a part of the movie."

Benedict Cumberbatch plays androgynous model-of-the-moment, All.

The film sees male models Stiller (Zoolander) and Owen Wilson (Hansel) attempt to reclaim their place in the world of high fashion.

Unfortunately, they find themselves irrelevant, branded "old" and "lame".

Zoolander was not a box office hit in 2001, but found legions of fans in the following years.

Stiller told the Press Association: "I felt bad for Derek after the first movie came out, because I think he thought he was going to have a bigger career after the movie, and nobody really went to the movie. And his modelling career kind of went down.

"Last few years there's been a resurgence and now he's like back on top really, back in the limelight. I think when he realised the first movie wasn't a documentary and it was actually supposed to be fun - because he tried to sue Paramount -he got very confused.

"Anyway it's nice to have him back."
