The 'Keeping Up with The Kardashians' star was honoured to have the entire Kardashian/Jenner clan attend his celebratory meal at Nobu in Malibu with only his sister Kourtney Kardashian and his fiance Blac Chyna not in attendance.

The sock-selling entrepreneur - who turned 29 on Thursday (17.03.16) - posed for a rare family portrait with Kim Kardashian West, her husband Kanye, Kourtney Kardashian and her estranged partner Scott Disick, his half-sister Kylie and Kendall Jenner and mother Kris Jenner.

Kim shared the picture on her Instagram account on Sunday (20.03.16) alongside the caption: "FAMILIA (sic)".

Rob had previously celebrated with his fiance Blac earlier last week when they took her son King Cairo - whom she had with ex Tyga, who now dates his half-sister Kylie - to Legoland.

Blac, 27, was reportedly not at the family function because she had work to do in Los Angeles however, it's believed she is keeping away from Rob's family because their relationship reportedly caused friction with his famous relatives.

A source previously revealed: "Chyna got him a few thoughtful gifts and she is giving him attention.

"Chyna has an appearance in Los Angeles on Saturday, so I think they are local and laying low."
