Robby Hayes is currently caught in the crosshairs of a federal investigation involving an alleged sex tape with Lindsie Chrisley.

But the Bachelorette star seems to be getting through it with a little help from his rekindled flame Scheana Shay.

After recently reuniting, they were spotted packing on the PDA Sunday at a pool party in Las Vegas.

He completed the look with a white baseball cap, white sneakers and a pair of sunglasses hanging off a silver chain necklace.

Hayes has been cooperating with federal investigators, recently submitting some evidence against Todd Chrisley.

Todd and son Chase Chrisley are being accused of extorting daughter Lindsie Chrisley with an alleged sex tape that also features Hayes.

Lindsie claims her father wanted her to lie under oath about her parents' tax evasion case.

Hayes recently told TMZ: 'At this point, this is all frustrating and this sex tape situation has been held over my head before. Hopefully all wrongdoings come to light.'
