To celebrate her 66th birthday, Caitlyn Jenner is seeking the help  of her daughter, Kylie Jenner and step-daughters Kim and Kourtney Kardashian for the party planning.

The former athlete has had a huge year: she came forward with her decision to transition from a male to a female during an interview with Diane Sawyer in April and then made her debut as a woman on the cover of Vanity Fair's July issue.

The Kardashian-Jenner clan met up at The Villa Restaurant in Woodland Hills, California, on Tuesday, October 27, the day before the Olympian’s birthday. They filmed scenes from the outing for at least one of their E! series, 'Keeping Up With the Kardashians' or 'I Am Cait', which was recently renewed for a second season.

Caitlyn looked rocker chic in a black printed top and black leather pants as she met her daughters for lunch. Pregnant Kim, 35, wore a blush colored maternity dress and matching coat, and Kourtney, 36, was sporting knee-high black boots and an olive jacket while carrying her daughter, Penelope, 3.
