Caitlyn Jenner poses with lookalike at the Life Ball

She has reportedly pulled out of son Brody Jenner's nuptials in Bali this weekend because of 'lucrative work opportunities'.

And Caitlyn Jenner spent Friday side-by-side with a lookalike, model Yasmine Petty, as they led the star-studded arrivals of the Life Ball, which kicked off in Salzburg, Austria on Friday.

The reality star, 68, was clearly transfixed by the transgender model, 30, as they posed together at the charity event.

Looking casual in a grey jumper and blue skinny jeans, Caitlyn was in great spirits as she joined fellow famous names, including Kelly Osbourne, Adrien Brody and Gilles Marini.

Caitlyn elongated her frame in classic black kitten heels as she let her chestnut tresses fall past her shoulders.

With only a touch of nude make-up, the former sports personality shielded her eyes with black wide-rimmed shades as she grew closer to the brunette bombshell.

Yasmine exhibited the same level of signature Keeping Up With The Kardashians glamour as superstar Kim, wearing her hair long and glossy with large shades covering her eyes.

She slipped her buxom figure into a skin-tight black mini dress and thigh-high lace-up boots.

Throwing a coquettish smile, the brunette teamed her risque look with a chic black coat and large sunglasses.
