If even the children of celebrities think their parents are mortifying, then there's not much hope for the rest of us, writes Deirdre Reynolds
With her movie-star looks, red carpet lifestyle and celebrity hubby, Kate Beckinsale is easily one of the coolest women on the planet.
To her 13-year-old daughter Lily, however, the British actress is just a complete embarrassment.
Underworld star Kate (38) has revealed how her daughter by former boyfriend Michael Sheen wouldn't be seen dead with her famous mum.
"She's become a teenager, so all of a sudden I became a whole lot more embarrassing than I'd ever been in the past," says Kate, who's married to director Len Wiseman.
"I do have a tendency to be that sort of awful mother who thinks she's really hip, so right now I have to give her space."
At least it gives her something to chuckle about with fellow yummy mummy Kate Winslet the next time they bump into each other on the red carpet.
Not even scooping an Oscar in an Yves St Laurent frock could stop the mum of two from shaming her tween daughter Mia (11) in 2008.
"[Afterwards, Mia said] 'I need to talk to you about the dress -- it was grey'," says 36-year-old Winslet, who won Best Actress for her role in The Reader. "She was absolutely mortified I wore a grey dress."
But the two Kates are not alone -- 88pc of teenagers admitted to regularly being left red-faced by their mums in a recent survey, with dodgy jokes and public affection among the top offences.
Never mind the 'terrible twos', now it's the 'terrible teens' testing parents.
"Parents often ring me when their kids get to this age," says Beth Fitzpatrick, director of Access Counselling in Crumlin. "Having been really close for the first 12 years, they panic when their child suddenly wants nothing to do with them.
"But it's perfectly normal for teenagers to be embarrassed by their parents.
"Think of it like this," she explains. "Up until the magic age of 13, a child's world revolves around their parents, teacher and school pals.
"Once they start going through puberty, though, their friends become the most important thing.
"My own youngest son used to love me walking him to school," recalls gran-of-10 Beth. "Then at 11, one day he just turned around and said: 'Would you mind walking behind me?'"
Just like Demi Moore and daughters Rumer (23), Scout (20) and Tallulah Willis (18), though, it is possible to survive teendom together.
"The key thing is to give your teen a bit more space," advises therapist Beth.
"If you continue to treat them like a five-year-old, your relationship is going to suffer big-time."
"It's all about knowing when to let go -- and more importantly, knowing when to be there."
