Mark Wright had a secret relationship with a contestant on Take Me Out while presenting the show's ITV2 spin-off.
The TOWIE star-turned-TV presenter was hosting the show when he enjoyed a nine-month affair with contestant Natalie Hawker, something which is strictly against ITV's rules.
Speaking to the Sun about their relationship, Natalie said: "He was scared. It was ridiculous. He would be introduced to me by the crew as a stranger. The first time he even knew I was on the show was when we met on set. I didn’t say anything and neither did he. But for three episodes of The Gossip he interviewed me like we were strangers. Afterwards he would text me begging me not to say a word."
Natalie was well known among viewers of the show for her 30GG bust size, and said it was this that first attracted Mark's attention, as he saw her in a restaurant in her native Bristol and asked her if they were real or fake.
She added that they first spent the night together when Mark was in a relationship with Lauren Goodger last February, but Mark had lied to her and said their relationship was over.
Natalie has now warned the hunk's current girlfriend Michelle Keegan about his behaviour and advised her to be careful.
Natalie told the newspaper: "I must have been mad thinking he would want a normal relationship. He loves himself and the idea of fame, so being with a soap star will suit him for now. But Michelle should know what he's like and how he thinks. She probably thinks Mark is as sweet as I did. The truth is he is a cheat who uses women to get what he wants then runs a mile."
