Chloe Lewis revealed on Sunday night's The Only Way Is Majorca that she'd seen Megan doing some dirty dancing with another man while at a pool party in Marbella.
It led to fears Megan and Pete's strong romance could be rocked…
But that's not the case.
In tonight's episode we'll see Pete telling Chloe he doesn't believe the rumour and nothing will come between him and Megan, before having a heart to heart with Megan to assure her he's on her side.
Megan had been worried about Pete's state of mind when he went super silent after the rumour was revealed, before vowing to confront Chloe and then walking off. Megan was left in tears.
It's not the first time Pete has been loyal to Megan when rumours were flying around. Earlier this year he backed her up following allegations she'd slept with Chloe's now-ex-boyfriend Jake Hall.
Megan and Jake both vehemently denied it but Chloe didn't seem to believe them, and her romance with Jake eventually crumbled. Pete, however, believed Megan and stuck by her.
This time around, he's doing the same, recently saying: "Where [Chloe's] relationship has broken down, which is nothing to do with us - it's been broken down for f**king years, obviously she sees me and [Megan] quite happy it's probably got to her quite a bit... all this crap she is talking about in Marbella, [Megan] grinding on people, she was out there with all my mates...
"When you look at strong relationships, they don't fall apart based on rumours, they fall apart based on facts. Chloe's got no facts. The only fact of it is, is that she's unstable and her relationship was pretty much over before me and Megan got together, and before Megan was even around on the scene."
