Jordan Firstman is ripping the HBO Max hit “Heated Rivalry” … he says the show has a bunch of unrealistic gay sex scenes.

In an interview with Vulture, the openly gay actor repeatedly slammed the streaming show, saying … “I’m sorry, I watched those first two episodes … and it’s just not gay. It’s not how gay people f***.”

Jordan filmed real, non-simulated sex scenes in his 2023 flick, “Rotting in The Sun” … so he would seem to be kind of an expert here.

He also had sex scenes in his own HBO show, “I Love LA,” so this is some HBO on HBO hate here.

“Selling The OC” star Alex Hall says she wouldn’t sell Diddy a home in Orange County, California if he came calling after prison … even if his budget was $30 million.

Alex was our guest host Friday on “TMZ on TV” and we asked her straight up if she would work for Diddy as a realtor when he’s done serving his sentence in New Jersey.

Diddy’s twin daughters are hobnobbing with Hollywood celebs, which has us wondering how Diddy will be received when he’s out of the pen … and it sounds like there will be a mixed bag.

Alex says she wouldn’t sign on to be Diddy’s realtor, but she does tell us how she would be able to squeeze some money out of the deal without touching it with a 10-foot pole.

After Andy Dick‘s drug overdose this week provoked panicked concern among friends, he’s checked himself into rehab … Dick himself tells TMZ.

Andy tells TMZ he is currently entering a rehabilitation facility in the Palm Springs, California area.

Andy was very animated on the phone with us … he’s cracking jokes and it’s clear he’s ready to commit to clean up … he tells us he’s grateful to be getting help.

Andy tells us … “Jenny Gimenez is my sister who saved me with Tim” … Tim Ryan is Jen’s husband. They’re both sober.

Jennifer was on “Celebrity Rehab” with Andy. They’ve been friends for 20 years.
