Celebrity Blac Chyna Vows to Help Train Fiancé Rob Kardashian for the 'Next Five Weeks Every Day' - Reveals His Current Weight Is 248 Lbs. The couple got engaged on Monday By Karen Mizoguchi Updated on December 8, 2020 10:56 AM Share Tweet Pin Email Photo: AKM-GSI Blac Chyna is determined to help fiancé Rob Kardashian slim down. The newly engaged couple were spotted together in Los Angeles on Wednesday dressed casually and matching in black Yeezy sneakers. Blac Chyna’s 7-carat diamond ring was certainly not hard to miss as she showed off her massive rock during the outing. During their excursion, the 27-year-old mother of one publicly announced on Snapchat that she has taken the initiative to help her man continue to lose weight. https://www.instagram.com/p/BD4RqYBFkdD/ https://www.instagram.com/p/BD4MHQvlkTm/ “So I need to consent, do you give me permission to train you for the next 5 weeks every day?” Blac Chyna says in a selfie video of the couple. “Of course,” Kardashian, 29, agreed. And she wasn’t kidding around. The model also recorded her future husband stepping on the scale, revealing his current weight of 248 lbs. So why 5 weeks? “Getting Rob ready for my birthday May 11 – 5 weeks,” Blac Chyna captioned one of Snapchat clips. Love appears to be the best motivator for Kardashian to lose weight as he continues to be on his path to a more active lifestyle. https://www.instagram.com/p/BD4L8GTlkTJ/ https://www.instagram.com/p/BD4R4qgFkdp/ In comparison to late December when the former reclusive reality star was diagnosed with diabetes after battling depression and gaining 100 lbs., he appears thinner and maintains a more healthy diet regimen. Kardashian popped the question Monday night – just 10 weeks after they took their relationship public. That same night, Blac Chyna – who is “more than excited, thrilled, and just super happy” to be become the future Mrs. Kardashian – celebrated her engagement with a party at Ace of Diamonds strip club in LA. https://www.instagram.com/p/BD2HpgvREp6/ The venue posted a video of Blac Chyna and Rob on Tuesday looking all smiles as they partied together with friends surrounded by fans along with confetti and sparklers. “About last night… She said YES,” a message read in the short clip that also showed Blac Chyna gleefully flaunting her diamond engagement ring to all. Kardashian’s family members including his sisters Kourtney Kardashian, Kim Kardashian West, Khloé Kardashian, Kendall Jenner and Kylie Jenner as well as momager Kris Jenner all remain silent on Rob’s engagement while they enjoy a snowy vacation in Vail, Colorado.
