InstagramKhloé Kardashian turned heads at her own 31st birthday with a risqué look as she celebrated with her friends and family, including Kourtney Kardashian and her eldest child, son Mason Disick, 5.
The birthday girl wore a black plunging outfit that showed major cleavage, as seen in a cute selfie of the three snapped by Kourtney, 36, and posted on Khloé's Instagram page on Saturday.
"A little birthday bowling with my faves," Khloé said.
The group was also joined by sister Kylie Jenner, 17, a fan of the plunging look herself, who sported at the party a modest white long sleeve crop top and black pants.
"Bowling babes," Khloé wrote.
The Keeping Up With the Kardashians star also received a birthday cake that is so money...as seen in a pic Kylie shared.
"Knock knock I've got a delivery! @khloekardashian #khloMoneyBday lets paaartyy," she wrote.
Also on Saturday, Khloé also received sweet online birthday wishes from other family members, including Kris Jenner, who was in France to watch Kendall Jenner, 19, walk the runway at Paris Fashion Week, pregnant sister Kim Kardashian, 34, who was in England to watch husband Kanye West, 38, perform at the 2015 Glastonbury Festival, Caitlyn Jenner, 65, and brother Rob Kardashian, 28.
He returned to Instagram last month after largely staying out of the limelight for more than a year.
"LOVE YOU more than life!" he wrote.
