Has Blac Chyna called it quits with Rob Kardashian following her cheating scandal? The 28-year-old model fuels split rumors after she ditched her engagement ring during a solo outing in West Hollywood on Friday, February 10.

In some photos obtained by X17online, Blac could be seen running errands in her purple Lamborghini. The "Rob & Chyna" star donned a black beanie paired with blue tracksuit and fur slippers. According to the photographer, she deliberately showed her ring-less finger to paparazzi as she held her left hand in front of her face when exiting a parking lot.

Rumor has it, Rob might be canceling his wedding to Blac after she was caught cheating on him with another man earlier this week. When learning about the news, "Rob would definitely not be happy," a source told PEOPLE, "One of their main issues is that Rob doesn't trust her. Even rumors of Chyna getting close to other guys, will cause another epic fight."

While Rob and Blac should be already planning their wedding following the arrival of their daughter Dream, "there haven't been any wedding talks." The source added, "They are together, but not living together. It's a bizarre situation. They are still engaged and Chyna wears her ring. There haven't been any wedding talks though."
