Khloe Kardashian's husband Lamar Odom skipped her sister's birthday dinner amid new allegations he cheated on her.
The 'Keeping Up with the Kardashians' star, 29, attended a family dinner to celebrate her half-sister Kylie Jenner's 16th birthday at Nobu restaurant in Malibu, California, alone on Saturday night.
A source told gossip website RadarOnline.com that Khloe, who is devastated by the rumours, was accompanied by two bodyguards rather than her husband of four years, just days after lawyer Polina Polonsky claimed she had a passionate six-week affair with him earlier this summer.
Los Angeles Clippers star Lamar was previously accused of having a yearlong affair with Jennifer Richardson until March 2013.
Kylie's sister Kim, 32, who has been in hiding since she gave birth to daughter, North West, in June, and her boyfriend Kanye West also missed the party.
But her oldest sister Kourtney, 34, used the opportunity to put on a united front with her boyfriend, Scott Disick, at the gathering after male model Michael Girgenti filed a paternity lawsuit against her, claiming he is her son Mason's real biological father.
The couple were joined by Mason and their 13-month-old daughter Penelope.
Kylie reportedly received a number of gift cards to her older sisters' store Dash for her birthday as well as a giant cake.
Despite several family members missing her dinner, she wrote on Twitter last night: "Thank you to everyone for the bday wishes and making yesterday so special! Blessed! (Sic)"
