Blac Chyna Hangs Out With Beyonce's 'Super Sweet' and 'Beautiful' Mother Tina Knowles in Las Vegas

Blac Chyna's trip to Las Vegas keeps getting better and better!
The 28-year-old model, who is currently pregnant with fiancé Rob Kardashian's first child, took to Instagram on Sunday to reveal her most recent celebrity encounter -- none other than Beyonce's mother, Tina Knowles!
Chyna, dressed in a black-and-white jersey top and black hat, was still rocking the pink-colored tresses she sported one night earlier at Mariah Carey's #1 to Infinity residency show at Caesar's Palace. Knowles, who was in town with her husband, Richard Lawson, kept it classy and chic in a pair of oversized sunglasses, a bright red lip and a long-sleeved shirt. (Meanwhile, her daughters were in New Mexico celebrating Solange's 30th birthday.)
"It was wonderful seeing Mrs Tina," Chyna captioned a snapshot of the two. "She's super sweet & beautiful."

Her fans were equally excited about the rendezvous, commenting things like, "Welcome to the Beyhive, Chy!" "YYYYAAAASSSSS HUNNI WALK WITH ROYALLY CAUSE YOU WERE MADE FOR GREATNESS," and "OMG! All Hail The Queen!!"
As if that wasn't exciting enough, Chyna had another exhilarating thought on her mind. "Can't wait until the baby is here," she shared via Snapchat.

Chyna's clearly been enjoying her time in Sin City. As ET previously reported, she was pulled on stage during Carey's Saturday night show, where she was treated to a lap dance from one of the "Hero" singer's sexy male dancers.
Later, Carey headed to 1 OAK nightclub for her first-ever DJ'ing gig. The diva stunned in a risqué corset top, which she paired with fishnet stockings, suspenders and a leather jacket.
