A whole new meaning to going public! Rob Kardashian supported his girlfriend, Blac Chyna, during her topless photo shoot on Thursday, February 4. The model, 27, wore a teeny bikini for the sexy beachside poses, and at one point was photographed without her top on.

The risqué campaign was for alkaline water company 138 Water.

While Chyna posed for photographers and flaunted her backside — all while clutching a water bottle — reclusive Arthur George sock designer Kardashian supported his lady love from the sidelines.

Clad in an oversize black T-shirt and workout shorts, the 28-year-old — who was diagnosed with type 2 diabetes last year — looked happy to be there for his girl. After her shoot wrapped, Chyna and Kardashian — who looked smitten with each other — perfected a secret handshake.

As previously reported, the makeup artist is helping Kardashian shed weight. The reality personality has struggled with weight gain and depression the last few years, which has been documented on his family’s hit reality series, Keeping Up With the Kardashians. Chyna, who was previously engaged to rapper Tyga — who is now dating Kardashian’s youngest sister, Kylie Jenner — has hired an online personal trainer and, per her Snapchats, has been cooking healthy meals for her boyfriend. 

A source told Us Weekly the two “bonded over their pain” after they both “felt f--ked over by the family.” (Chyna used to be friends with Rob’s older sister Kim Kardashian prior to the model’s split from Tyga, while Rob has felt unsupported by the clan.)
