LOS ANGELES, Jan. 25 (UPI) -- Rob Kardashian and Blac Chyna sparked dating rumors with a new photo Monday.
The 28-year-old reality star and 27-year-old model sent fans into a frenzy by appearing to embrace in an Instagram post. Blac Chyna simply captioned the picture, "The beginning" with a clubs emoji.
Kardashian's tattoos were immediately recognizable, although his face isn't visible in the snapshot. Sources told TMZ the pair have been together "almost non-stop" for several days.
Blac Chyna was friends with Kardashian's sister Kim Kardashian until the siblings' half-sister Kylie Jenner started dating Tyga. Blac Chyna and the 26-year-old rapper were previously engaged, and share 3-year-old son King Cairo Stevenson.
Amber Rose, who is best friends with Blac Chyna, feuded with Khloe Kardashian over Tyga's relationship with Jenner in February. The 32-year-old model insulted Kim Kardashian and her family on Twitter after calling Jenner, who was 17 at the time, a "baby" in a radio interview.
Jenner went public with Tyga at her 18th birthday party in August, and was still dating the rapper in November despite breakup rumors. Sources recently told People the couple are together but "not on the best terms" following rumors Tyga cheated with model Annalu Cardoso.

Kardashian previously dated The Cheetah Girls star Adrienne Bailon from 2007 to 2009. The reality star gained 100 pounds in the past three years and has largely retreated from the spotlight, but is reportedly doing well following a health scare in December.
