Brandi Glanville and Alexis Texas Have Mutual Associates in Porn Business

Brandi Glanville‘s a ‘Real Housewives’ star with real friends in the porn industry … which is how she linked up with Alexis Texas for their steamy photo shoot.

The reality star and actress tells TMZ … Alexis was in town for business and asked Brandi to hop on her podcast “Private Talk with Alexis Texas.”

The two hit it off … and, they even realized they know the same people in the adult film world. Brandi’s pretty non-judgmental about that kinda thing — the parents of her son’s best friend are actually in the industry too.

Glanville says she and Texas had such a fun time chopping it up, that they headed to the roof to get some sun … and, they took a few sultry snaps, too.

We shared the pics with you … Brandi and Alexis hanging around the pool, tiny bikini bottoms on revealing both of their impressive backsides.

They even took a pic where Alexis bent over at the waist and balanced a glass of wine on her booty … a pro move only the likes of Alexis and Kim Kardashian on a magazine cover can handle.

Brandi’s ensemble certainly took the focus off her face … which has been through the ringer because of a mystery illness that Dr. Terry Dubrow swears isn’t a parasite.
