Who knew that the cast members of "The Real Housewives" franchise are friends?

"The Real Housewives of Beverly Hills" star Lisa Vanderpump recently showed support for fellow Housewife Teresa Giudice, who was sentenced to 15 months in prison last week.

Vanderpump's support for "The Real Housewives of New Jersey" cast member was revealed after a Twitter user called her out on not commenting on the Giudice's recent legal troubles.

"@LisaVanderpump you know I love you so much. But I'm shocked that you haven't commented on Teresa's situation. A DUI gets less time than her," wrote Twitter use letsgoflyakite.

Lisa Vanderpump made sure to slam any and all rumors that could arise from the tweet by immediately responding with, "I have supported her and called her personally. Not everything needs to be on display, have a goodnight."

The RHOBH cast member had been supportive of Teresa Giudice and her family since the mother of four pleaded guilty with her husband Joe Giudice several months ago, according to Bravo.

"'Hey, I'm thinking of you, and I know things will work out in the end. I just don't know how, or what, you're going to have to get through to go there. I support you,'" the "Vanderpump Rules" star told Teresa Giudice at the time, according to E! News.

Vanderpump added, "I can only imagine, it has to be a nightmare to be in the midst of that. She's always been a lovely woman. I know that from first-hand experience."

Lisa Vanderpump is currently dealing with her own drama while filming for RHOBH. Photos surfaced showing the restaurant owner getting in what looked like a heated argument with Yolanda Foster and Brandi Glanville during their cast trip to Holland, according to the media outlet All About RH.

Vanderpump had opened up about season 5 of RHOBH, assuring fans that it's going to be "better than last season," according to Extra TV.

"I can't say it's all plain sailing, that's for sure. At it's best, it is not an easy situation sometimes," stated Vanderpump.
