Lisa Vanderpump defends Andy Cohen and quashes the lawsuit against Rachel Levis

Lisa Vanderpump comes to her old friend's defense Andy Cohen amid some new accusations – and in the same breath… she takes a swipe at Rachel Leviss.

The former 'Housewives' star — who obviously got her spinoff show on Bravo — arrived at LAX on Friday as she landed back in the city… where our photog ran into her and asked her all about the latest drama going on in the reality world, and there is a lot.

To start, our cameraman asked about it Leah McSweeney's claims a new lawsuit she filed this week against the Bravo honcho … claiming he had used cocaine, not to mention claiming that Bravo in general was a toxic hellhole that coaxed their stars into drinking and debauchery.

Well, Lisa has some thoughts on that… and she goes to bat for AC here, telling us that she's never seen him use hard drugs – nor does she know that he's anything like what Leah describes.

On the idea of ​​Bravo pressuring 'Housewives' to drink on set… Lisa says what many of her contemporaries have already made it clear — the stars are adults, and they don't have to do anything they don't want to do. Basically…she's calling BS about Leah's suit.

Finally, Lisa weighs in the legal battle that arises in her own world…namely Rachel filing charges Tom Sandoval And Ariana Madix including revenge porn.

She doesn't have nice things to say about that either – noting that Rachel probably should never have compromised herself on camera the way she did if she didn't want it to come out.

However, we clarify that Tom allegedly recorded her from his phone and distributed it to the cast… but even then, she doesn't have much sympathy for her ex-employee.
