Blac Chyna poses with Lamar Odom while her ex Tyga says co-parenting with her is 'better than ever'

The exes of the Kardashian-Jenner family were all in one place on Wednesday night.

Rob Kardashian's ex-fiancee, Blac Chyna, attended the launch event at the Beverly Wilshire Hotel, and in a bizarre turn of events, hung out and posed for photos with Khloe Kardashian's ex-husband, Lamar Odom. This comes just weeks after Odom told ET that he's praying for Rob, and hoping that the 30-year-old reality star will "live and learn through" his recent relationship drama.

In addition to Chyna and Odom, Bella Thorne -- the rumored on-again, off-again fling of Kourtney Kardashian's ex, Scott Disick -- was also at the event as well as Kylie Jenner's ex-boyfriend, Tyga, who shares a son with Chyna.

While Chyna and Rob recently aired out their drama on social media -- which ultimately led to the 29-year-old model being granted a restraining order against her ex -- Tyga told ET's Lauren Zima at the party that his relationship with the mother of his 4-year-old son, King, is "better than ever."

"I got an amazing son. I'm blessed," he gushed. "He's the best man, honestly. Like, he's such a blessing."

As for how he was feeling about seeing Chyna at the event, the 27-year-old rapper insisted, "We're good, we're good, appreciate it."

Like Tyga, Chyna was also feeling positive on the red carpet. "I'm doing good. I'm just feeling blessed right now," she told ET. "I'm so excited to be here."

Chyna went on to praise her son, King, and her and Rob's 8-month-old daughter, Dream Kardashian. "Oh my god! Like, they're amazing, yeah. They're doing well," she exclaimed. "They're doing well for sure."
