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."
Will Ferrell has returned to the role of Derek and Hansel's fashion world enemy Mugatu - who starts the film in prison, serving a sentence for the attempted assassination of the prime minister of Malaysia 15 years ago.
But he is soon out and up to his villainous tricks, declaring: "Prison changed me. I am bad to the core now."
Explaining how he prepared for the role, Ferrell said: "I watched the first movie again prior to shooting, going: 'Oh I'd better remind myself how Mugatu sounds and acts and moves'.
"But once I got in the first wardrobe fitting and got the wig on and the little tiny dog in my hand, I was right back where I was 15 years ago."
He added: "There were a couple of times working with Ben where I would scream at him as Mugatu and he would look so stupid that I couldn't hold a straight face.
"Working with Kristen Wiig is always a constant battle to not break up, so that's a sign that you're having fun."
Wiig joined Zoolander No 2 as a newcomer, putting on an almost-unintelligible accent and layers of make-up to play fashion mogul Alexanya Atoz.
The make-up took four hours to apply every day.
"The good thing for me is that I couldn't move my face, even if I tried, because of all the prosthetics that I had," she explained.
"So it was actually kind of hard to smile. So I would just laugh on the inside."
Penelope Cruz is another newcomer, playing motorcycle-riding Valentina, an Interpol special agent (global fashion division).
Valentina is forced to enlist the help of Derek and Hansel as she attempts to get to the bottom of the spate of celebrity killings. All the victims mysteriously snapped photos of Derek's "looks" in their dying moments, with Bieber declaring: "Peace out world".
Cruz said: "I was so excited. I'm a huge fan of the first one, and when Ben called me, I was so happy."
The red carpet event featured a successful bid by Stiller to break the record for a photo taken by the world's longest selfie stick.
Surrounded by the cast of the film, fans, red carpet guests and the press, he hoisted the selfie stick in the air and was able to take a group photo.
The record breaking attempt was verified by a representative from the Guinness Book of World Records.
:: Zoolander No 2 is released in UK cinemas on February 12.
