CELEBS Go Dating star Ryan-Mark has an explosive row with love guru Paul Carrick Brunson tonight after he's slammed as the "rudest person" he's ever met.
The 21-year-old was scored -3 out of ten from his date - the worst in the dating agency's history.
Ryan-Mark laughed off the bad review, but dating expert Paul wasn't impressed.
In a teaser clip from tonight's episode, Paul insisted: "You are literally the most rude person I have ever met.

Ryan-Mark shook his head as he disagreed with Paul's claims.
Paul added: "Here's the problem - you're not progressing."
Ryan-Mark fired back: "Yeah because you're giving me s*** dates."
