She announced on her wedding day she'd have no problem stealing another bride's husband if he was hotter than hers in this year's season of MAFS, and that's exactly what Botoxed beauty Davina Rnakin has done!
The ink barely had time to dry on her marriage certificate to tradie Ryan Gallagher when the busty brunette embroiled herself in the show's biggest scandal so far – an illicit affair with Tracey Jewel's husband Dean Wells.
They locked eyes for the first time at an explosive dinner party on Married at First Sight and it wasn't long before the sneaky pair started secretly swapping flirty text messages, despite both being married to other people.
While Davina has hinted she's struggled to stay with one partner for longer than three weeks at a time in the past, 40-year-old Dean's betrayal seems all the more shocking, given he could barely keep his hands off his wife Tracey, 34, on their wedding night, calling her "super sexy!"
"Davina and Dean started flirting at the first dinner party. She found a way to contact him and suggested they 'catch up' sometime," spills a set insider.

Tracey was totally heartbroken to discover Dean's infidelity during a commitment ceremony later in the series.
"She'd just had an amazing wedding and honeymoon and it was obvious she wanted to give the relationship a go," our source adds.
"They had a strong connection and she had no idea Dean was looking elsewhere. She was shocked, hurt and heartbroken."
Adding to Tracey's turmoil, we're told Dean has a change of heart, ditching Davina and begging Tracey for forgiveness.
"Dean completely blindsided Davina by announcing he still had feelings for Tracey, and told her he loved her.
"He broke down and cried. As for Davina, everybody started to call her a man slayer," adds the insider.
