Ulrika Jonsson enjoyed a cheeky dig at fellow Celebs Go Dating star Marty McKenna as she flaunted her lingerie.
Fans are currently watching the Gladiators legend look for love on the E4 programme.
Ulrika stunned in her latest Instagram post, flaunting her physique before referring to herself as a "worm" in a cryptic caption.
She also couldn't resist a poked at Geordie Shore and Ex on the Beach start Marty in her latest upload.
Her fellow contestant's hilarious blunder in week one of the show saw the fun-loving reality star get Ulrika's name very, very wrong.
Poor Marty got all tongue-tied in a chat with agency experts Anna Williamson and Paul Brunson.
Oblivious Marty, 27, called her "Urethra" - and it left viewers in stitches.
The urethra, of course, is in fact the tube inside the penis that men urinate through.
The star, 54, donned a black bra and showed off her abs and tattooed arms, captioning the shot: "Finally. This worm has turned.
"Can feel the sea change within. It’s palpable.
"Might have been a while coming. But it’s here now. And change is a coming.
"Keep your BS and your bailing; your fears and insecurities; keep your desire for intrigue - I’m not your subject."
Ulrika then added. "Call me ruthless. Or just Ulrika. "(Not Urethra….. @marty_gshore)".
Anna, one of the show's dating specialists, said: "THERE SHE IS!!!!!!!! (and we ARE right the best is yet to come gorgeous lady) xxx,".
In a chat with the Daily Star, the host branded Ulrika "a naughty little minx".
Anna said of the star: "Ulrika is young at heart and when I found out she was coming on the show I was so excited.
"She's a naughty little minx. She has a very young heart and a potty mouth and I think for Ulrika we do try to stretch her repertoire on the show."
Ulrika has opened up on the show, admitting she prefers the "younger" man.
Viewers have seen her go on a number of awkward dated after she explained she is tired of being single.
