Blac Chyna Buddies Up with Lamar Odom, Reunites with Ex Tyga at iGo.Live Launch Party!

Blac Chyna happily flashes a smile alongside Lamar Odom while attending the launch event for iGo.Live on Wednesday evening (July 26) at the Beverly Wilshire Hotel in Beverly Hills, Calif.

The 29-year-old reality star arrived with her pal Sandra Denton (Pepa of Salt-n-Pepa) but shortly met up with Lamar once the bash got going.

Blac also found herself in the same room with her ex Tyga, who showed up solo to the event. They were previously engaged and share a 4-year-old son named King Cairo.

Tyga dated Kylie Jenner while Chyna got engaged to Rob Kardashian and both couples later called it quits. Meanwhile, Lamar was married to Khloe Kardashian for several years before filing for divorce in December 2013.
