Renner, who shares a child with Washington, appeared on the podcast along with internet personality Charleston White - and things got out of hand.
In a clip from the show, Renner can be seen sitting on top of White and giving him a lap dance to the guest's surprise while she flash her black panty.
Then, Renner splashed water on White - who is believed to be in his early 50s - and the host of the show as well.

Renner, 31, and Washington, 25, started dating sometime in 2020 before breaking up the following year, with the NBA player writing a vague tweet about someone 'faking it all along.'
Renner, who has been linked in the past with James Harden, Lil Uzi Vert and a slew of other celebrities, has previously denied suggestions that she somehow entrapped Washington into having a child.
'That was his choice,' she said on the 'Off the Record' podcast with DJ Akademiks.
'You asked me to move in with you. You wanted me to have your child at 22 years old.
'And here we are. I told you, 'I'm ok to wait. I'm not in a rush," she added.
Renner told Akademiks that she and Washington met when she was 26 years old, while he was playing at the University of Kentucky.
Washington is entering his fifth NBA season and has made over $17million to date in his pro career.
He signed a three-year, $48million extension with the Hornets this summer.
