The TOWIE star, 28, hit out via Instagram after it was reported by a newspaper over the weekend she'd been looking cosy with a man named Joey Morrison during visits to HMP Standford Hill.
Lauren said: "I don't normally do this but I feel I have to explain this situation that is in the press at the minute. This boy Joey Morrison is my friend and I have known him for many years."
She added: "Leave this at he's my friend and I have nothing else to say."
Lauren's last romance was with Jake McLean, whom she dated for four years before splitting in May. At the time, Lauren's rep said: "The break-up was amicable and there was no-one else involved. Lauren is feeling positive and looking forward to the future."
Her most high profile romance was, of course, with former TOWIE co-star Mark Wright, who is now happily married to Our Girl actress Michelle Keegan.
Essex original Lauren's getting ready to return to TOWIE this series, marking her first time on the show as a regular since series six. She did pop up during the Christmas special last year for a brief cameo.
But we'll have to wait a little longer to see her on screen as a rep told us she's not filming with the cast in Marbella.
Lauren announced her return over the summer, saying: "I said I would love to come in as Lauren so people can see who Lauren is. Nobody knows who I am. I've always been in drama or in a relationship on TV and now it's about me. I have no drama. I can go in and be one of the girls."
