The 31 year old bumped into her little sisters at the party.
Kim Kardashian and Mike Tyson were among the guests at Justin Bieber’s surprise birthday party on Friday.
Bieber celebrated his 18th at a bash thrown by his manager Scooter Braun and mother Patti Mallette, where guests also included his girlfriend Selena Gomez – who jetted in from Florida, where she has been filming ‘Spring Breakers’, for the occasion.
Many of Justin’s childhood friends flew in from Canada for the occasion, as did his grandparents and the young Kardashian sister, which ended up being a bit embarrassing for their 31 year old sister Kim. After running into her little sisters, she tweeted:
“The awkward moment when you go to a party and run into your little sisters! LOL.”
It’s ok Kim, Justin probably didn’t notice as he apparently spent most of the night with his girlfriend Selena.
A source said: “He was all over Selena the whole time, walking her around by the hand. He kept kissing her. It’s clear she was the best part of the night for him. He is so in love with her.”
Justin previously said he was planning a “low key” birthday celebration. He said: “My birthday, I’m going to hang out with my friends and family, have a little get-together; nothing too crazy.”
The Canadian singer was given a luxury sports car by his manager Scooter Braun during an appearance on the ‘Ellen DeGeneres Show’ last week but he was most impressed by a different gift. Asked what his best present was, he said: “I got a pool table, a purple one and it’s amazing. That’s probably my favorite.”
