Glamorous sisters Joan and Jackie Collins look fabulous at Beverly Hills luncheon #CarryGobySeanKellz #FutureGroupNG via @i_amreginaldjr

ONE celebrated their 80th birthday last year and the other will turn 77 this year, but Joan and Jackie Collins are not about to let age get in the way of their glamorous lifestyles.

The famous sisters looked remarkably youthful as they attended a luncheon in Beverly Hills, and could certainly give women half their age a run for their money.
As they arrived at the Beverly Hills Hotel, the ladies worked the cameras and posed up a storm in two rather different outfits.
Jackie, who received the Trailblazer Award at the event, looked chic yet sexy in a pair of black trousers, a matching top and a cream blazer.

The mother-of-four completed her look with black heels, a green pendant necklace and matching statement earrings as she stood with her hand on her hip.
Meanwhile, her older sister decided to flash some flesh and her golden tan by wearing a black and white patterned dress which featured a square neckline and long sleeves.
Joan teamed the knee-length garment with monochrome heels, a cream quilted clutch bag and pearl earrings as she pouted for photographers.

The 'Dynasty' star completed her youthful look with plenty of bright pink lipstick as she supported her younger sister.
Both ladies were sporting rather impressive blowdries and spent time mingling with US actresses Marilu Henner and Annabelle Gurwitch.
