Goldie Hawn may be 66, but the Oscar-winning actress still knows how to kick up her heels.
Photographs of a disheveled Hawn, falling into a waiting car outside London's Anabel's nightclub at 4:30 a.m., proved that the former "Laugh In" actress still has something of a colorful streak.
These days, Hawn is known more for her philanthropic causes and campaign to teach mindfulness to children. In fact, she was in London to celebrate the British launch of her children's charity, the Hawn Foundation, with daughter Kate Hudson and Hudson's fiancé Matt Bellamy, 33. Wearing a blue strapless gown, Hawn flashed her famous smile, appearing far younger than her 66 years.
But, when she emerged from the club nine hours later, Hawn looked worse for wear, her bangs hiding bleary blue eyes and with a goofy smile plastered on her face. She had to be helped into a car, but still managed to miss the seat and fall backwards, revealing still shapely legs.
Earlier, a more pulled together Hawn made appearances for her latest book, "10 Mindful Minutes," a guide for parents and teachers on teaching children yoga and meditation.
The book arrives in bookstores about the same time as a tell-all book by Hawn's ex-husband, Bill Hudson, the father of Kate and Oliver Hudson. Hudson's book, "2 Versions: The Other Side of Fame and Family," presents a darker portrait of the woman he calls "America's Sweetheart."
"She is hard, she is cold, she is a control-freak," he told Daily Mail writer Christopher Wilson, author of "Absolutely…Goldie." "She has this new book about how to keep children happy, but look what she did with her own kids."
Hawn's rep did not respond immediately to ABCNews.com's request for comment, but she recently said about the book and her second husband, "I just feel a little sad."
Hudson, who was married to Hawn from 1976 to 1980, claims that after they split up, Hawn thwarted him from seeing their children and painted him in the press as a father who walked out on his kids.
He says the real story is Hawn wanted to have an open marriage and ran off with French actor Yves Renier, when Oliver was three and Kate, just four months. Hudson filed for divorce but took care of the kids while Hawn was away with Renier for nearly a year.
After Hawn got together with longtime partner Kurt Russell - they have a son, Wyatt - Hudson said his access to the children became even more limited and ultimately Hudson gave up on trying to see them.
"I bitterly regret that. I should have fought all the way," he told Wilson. "It was a formative time for Kate, given that she was just 12. Maybe my children feel I didn't fight for them."
Hudson admits that today all he sees of his children - Oliver Hudson, 35, is also an actor - is on screen or in print, and he has had no contact with his grandchildren. Kate Hudson, 32, recently gave birth to her second son, Bingham, with Bellamy and has an 8-year-old son, Ryder, with ex Chris Robinson, frontman for the Black Crowes.
Kate Hudson has also spoken out about their estrangement. Following her breakout role in "Almost Famous," the then 21-year-old told Vanity Fair that her father "doesn't know me from a hole in the wall. But I don't care. I have a dad [Hawn's longtime companion, Kurt Russell]. The bottom line is, you call your kids on their f***ing birthday. I'm glad I had a dad who was there on my birthday."
Bill Hudson shot back that he was there for his kids and accused Kate of trying to beef up her story for the press.
"Kate is very talented and sweet and I love her dearly," he told the New York Daily News. "She's had a life of privilege from both parents. And the only thing that she really has to talk about is emotional devastation; that she's exaggerating."
With his book, the gloves were off. He wrote, "I love Kate, but … She has done stuff which is just awful. She is a spoiled brat in my eyes … I should meet my grandchild and she should help her grandmother."
