Rob Kardashian and Blac Chyna 'celebrate engagement at strip club'

Rob Kardashian and his new fiancee Blac Chyna reportedly toasted their engagement at a Los Angeles strip club.

The model sparked speculation the pair were engaged to marry on Monday night (04Apr16) when she posted a picture of the pair looking loved-up on her Instagram page, and a large sparkler could be seen on her ring finger. In the caption, she wrote, "YES !...!...!"

She was also spotted wearing the bling when she headed to the Ace of Diamonds strip club on Monday night with Rob and her mother Tokyo, who flew into the city to meet Rob over the weekend (02-03Apr16).

Sources tell TMZ.com Rob popped the question on Monday night and they toasted their engagement at the nightclub.

Their relationship has been moving fast since they began dating in January (16) and they are already living together. Blac's mother Tokyo appeared to give her approval on Instagram by posting a picture of herself and the couple.

The model's friend Amber Rose also seemed pleased the news, by sharing their engagement announcement picture on Twitter and writing, "Congratulations to my Family @blacchyna and @robkardashian!!!"

His family will not be around to celebrate with him in person as they have jetted off on a joint vacation to an undisclosed location on Monday. His mother Kris Jenner, sisters Kim, Kourtney, Khloe and half-sisters Kendall and Kylie Jenner, and their partners and children have all gathered for the break.

Kris revealed she barely knows her son's new love to Australian radio hosts Kyle & Jackie O Show last month (Mar16).

"She seems like a really nice girl but I just haven't been around her," she shared. "I don't know much about their relationship. I haven't really seen her that much and I don't know her as well as everyone else."
