Rob Kardashian made his first full-body appearance, on Monday, after returning from Texas with girlfriend Blac Chyna.

As Rob made his way out of his dusty, black Bentley after the 2400-mile round trip, we got a good look at the troubled Kardashian's full body -- the first time we've seen him since May 2014, when he was catching a flight to Paris for sis Kim's wedding to Kanye ... which he ended up ditching.

Kardashian wore his signature black tee and shorts and, as we've seen, has grown a thick beard. Reports claim the reclusive reality star is in love with former stripper Blac Chyna, despite -- or perhaps BECAUSE -- she's the baby mama of his half-sister Kylie's boyfriend Tyga. "He wants to do whatever he can to piss off his family," a source tells X17online. "Rob wants his moment in the spotlight. He's sick of all the women in his family getting everything. He thinks it's his turn now."
