A month short of 90, leather-clad Dame Joan Collins is still a Wild One

One month short of 90, leather-clad Dame Joan Collins is still a Wild One

Posing in an 1980s Yves Saint Laurent leather jacket that her husband found in her wardrobe, it’s hard to believe that Dame Joan Collins will be turning 90 in six weeks.

She looks no older than when she first wore the jacket in her late forties.

Yesterday, Dame Joan looked like she stepped off the set of the classic Marlin Brando movie, The Wild One, showing off her slim figure by pairing the vintage jacket with tight black pants.

The photo was taken at home by her fifth husband Percy Gibson, who is 31 years her junior.

Alongside the photo, Dame Joan wrote, “Looking for the #wisteria that blooms only in #spring, wearing an 80s @ysl jacket #shoppingmycloset… wait! Looks like #ahubby found it!”

The secret to her looks, close friends say, is her happy life with Mr. Gibson – and a diet of avocados, smoked salmon and “a little bit of alcohol to keep life from getting too boring.”

A friend told The Mail on Sunday: “The happiness that her love for Percy brings makes her look so good, that’s her secret.”

Dame Joan, who has four grandchildren, walks, swims and exercises every week with a personal trainer, though friends say she’s given that up.

On May 23, the 1970s star of The Stud, who also played Alexis Colby in Dynasty, will reach the milestone of her 90th birthday — but she’s determined to keep it as quiet as possible.

“There won’t be a party,” says the friend. “She wants it all very low-key.”
