Ariana Madix & Other ‘Vanderpump’ Stars Donate Big to Friend with Brain Tumor

Ariana Madix opened up her wallet big time to help out a friend of the ‘Vanderpump Rules’ family … this after a major health scare that’s threatening their life.

AM was among several ‘VP’ stars to draw attention to the GoFundMe page of Jesse Montana — who’s a pal of theirs and who’s appeared on the reality show. He recently revealed he’s been diagnosed with a brain tumor, and he’s looking to raise funds for his hospital stay … ’cause he’s going into surgery on Monday.

Like we said … a lot of the ‘Vanderpump’ cast members have donated, but Ariana has shelled out the most by far — offering up a $9,000 donation to help Jesse.

In hopes that Jesse’s unexpected health woes don’t leave him with a financial burden, the GFM page has a goal to raise $100,000.

The cast began donating over the weekend … and other ‘VPR’ contributions include Katie Maloney giving $3,000, Scheana Shay dropping $2,000, Tom Schwartz and Rachel Leviss chipped in $500.

‘VPR’ alums Brittany Cartwright and Kristen Doute donated $100 and the show’s executive producer, Alex Baskin gave $250. The donations touched Jesse … who said in his IG Stories ahead of surgery Monday that he’ll “forever be shocked at how fast life can change.”
