Kris Jenner celebrated estranged husband Bruce Jenner's 64th birthday on Sunday (27.10.13).

The couple - who announced they have separated after 22 years of marriage earlier this month - put on a united front as the Jenner and Kardashian clans came together for a celebratory dinner for the former Olympian ahead of his birthday today (28.10.13).

Bruce's big day warranted not one, but two birthday cakes moulded after his favourite pastimes - with one cake in the shape of a golf ball and the other in the shape of a helicopter.

Kris, 57, posted a happy picture of herself, daughter Khloe Kardashian Odom and Bruce's son from a previous marriage, Brendon, on her Instagram account.

The trio appeared to be in the party spirit, sporting fake moustaches and brightly coloured party hats.

Kris captioned the snap writing: ''Just another family Sunday dinner!! (sic)''

Khloe, 29, led the tributes to her stepfather, revealing that she is ''blessed'' to have had two fathers - Bruce and her biological dad Robert Kardashian, who passed away in 2003.

She wrote on Twitter: ''Such a fun early Birthday dinner for my Brucey. I am so lucky!!! I was blessed with TWO phenomenal fathers!!! Family first. (sic)''

Khloe also posted pictures of Bruce's two cakes, adding: ''He deserves not one but TWO cakes. A few of his favorite things (sic)''
