Kim Kardashian exudes sophistication in a silk champagne gown as she leads the glamour at Diddy's extravagant 50th birthday party alongside husband Kanye West

Kim Kardashian joined her husband Kanye West, legendary producer Dr. Dre and his wife Nicole Young at Diddy's star-studded 50th birthday party, presented by Ciroc Vodka at his $40million Holmby Hills mansion in Los Angeles on Saturday evening.

The media personality, 39, pulled out all the stops for the glitzy extravaganza as she and her dapper partner Kanye, 42, mingled with the music industry's finest for the Bad Boy star's belated celebration, the Daily Mail reports.

In her true fashion, the KUWTK star accentuated her famous curves in a champagne-coloured silk gown, which came complete with a corset-inspired bodice and a complementary clingy skirt. 

Exuding Old Hollywood style, the reality star displayed her cleavage in the low-scoop ensemble, while carrying her possessions in a shell-inspired handbag.

The businesswoman ensured focus remained on her appearance by amping up the glamour with a flashy diamond bracelet, stud earrings and her striking wedding band.

Law student Kim continued to borrow style inspiration from the 50s as her tresses were dressed into glossy curls, while her radiant complexion was highlighted with dewy make-up.

Jesus Walks hitmaker Kanye certainly didn't let his wife down in the style stakes as he sported a classic black suit, tied in with a white dress shirt.
