Mikey Pembroke recently admitted that he and Natasha Spencer did the deed during filming – but it appears the blond beefcake's bedroom skills weren't enough to keep his "wife" from running straight back into the arms of her former boyfriend!
Yep, with Mikey, 29, having confirmed that the pair are no longer together, Natasha, 26, was spotted on a date with ex Andrew Vlahos in Sydney's Double Bay recently.
NW is told the couple dated on-off for five years – with Andrew even attending her MAFS wedding to Mikey.

However, things became "bittersweet" for Andrew when he realised Natasha was marrying Mikey, who he was friendly with during their days at St Joseph's College on Sydney's North Shore.
"Watching someone you care about walk down the aisle with another man isn't the most ideal situation," Andrew tells NW.
"I knew as soon as I saw Mikey's brother standing at the altar as the best man that Mikey was going to be the groom."
So what about his not-so-secret reunion with Natasha?
"We are always going to be close – the door will always be open," he says.
"We're always going to be in each other's lives. I'll always be there for her."
While her ex Andrew waits in the wings, Natasha's also been busted cosying up to a mystery muscle man!
The MAFS star and the tattooed hunk got up close and personal in Sydney.
Get yours, Nat!
Meanwhile, things may not have worked out with his bride Natasha, but it seems Mikey's still a bit sweet on her best man.
The groom has been sliding into Natasha's bestie Lincoln Alexander's DMs, with leaked messages between the pair revealing their very flirty repartee!
"Looking forward to having a time with ya," Mikey wrote to Lincoln, before later cheekily adding, "I love u."
Something you want to tell us, you two?!
Amanda Micallef and returning intruder Elizabeth Sobinoff have fuelled whispers they're involved in this season's shock couple swap.
Amanda – who is already having drama with wife Tash Herz – recently posted an Insta pic where she was holding hands with Lizzie.
"When you and your girls nails and rings are on fleek," she wrote.
She's been billed as the introverted science geek, but Connie Crayden might not be giving us the whole story.
The bride's Instagram is filled with pics of her partying in Europe and one insider tells us, "It seems a little suss... Also, she's got all those tatts. I reckon she's got a wild side."
A second production source tells us that Connie wasn't at all shy at the dinner parties.
"She was chatting to everyone like the life of the party."
