Happy Birthday, Blac Chyna!

The reality star turned 29 on Thursday, kicking off her celebrations one night early with a party with family and friends. While the bash appeared to be a blast, there was one person noticeably missing from the soiree -- the model's on-again, off-again beau, Rob Kardashian.

Kardashian's absence didn't seem to stop Chyna from having a good time, however. Her best friend, Paige, and mother, Tokyo Toni, were just a few of the ladies spotted in pics and videos posted to the birthday girl's Snapchat.

As of Thursday morning, there was still no sign of a special birthday message to Chyna on Kardashian's social media accounts. His last post was a photo of a few of his favorite socks from his Arthur George line, which were emblazoned with "Papi," "Baby Mama," "Baby Daddy" and "Hot Tamale."

Chyna and Kardashian, who share 6-month-old daughter Dream, were last spotted publicly together in April, stepping out to TAO restaurant in Hollywood, California, for a flirty date night.
