Joan Collins looks glamorous at her 90th birthday party

Dame Joan Collins and her husband Percy Gibson were in high spirits as they stood arm in arm at her 90th birthday party in London on Wednesday.

The actress was seen beaming as she waved from a balcony while standing next to actor Percy, who, at 58, is more than 30 years her junior.

Dressed to impress for the evening, Dame Joan looked as glamorous as ever in a white off-the-shoulder top and black trousers.

Husband Percy, born in Peru but half Scottish, stood out in a red, yellow and black tartan kilt that he wore with a black waistcoat and white shirt.

He completed his look by wearing a black leather sporran with silver details on top.

Several of Joan’s guests were seen carrying gift bags and packages, and one couple carried a bunch of pink balloons.

Joan was a popular lady, as countless bouquets of flowers arrived to celebrate her 90th birthday, which was on Tuesday.

Percy, Joan’s surviving husband, is more than 30 years her junior, a gap she dismisses in interviews with the line, “If he dies, he dies.”

The long-standing couple celebrated their 20th wedding anniversary last year with a star-studded party at Claridge’s.
