Call Security! Scheana Marie Warns Nemesis Brandi Glanville -- Don't You Dare Crash My Wedding

Sorry, Brandi Glanville. Your invitation to Scheana Marie‘s wedding didn’t get lost in the mail.

Throwing MAJOR shade at the Real Housewives Of Beverly Hills, the Vanderpump Rules star opened up about her upcoming nuptials to Michael Shay, telling RadarOnline.com that she’s going to pump up security just in case Brandi tries to be a wedding crasher.

“She is absolutely not invited. And if she tries to crash it, I will have security escort her to the street and throw her out,” the occasional pop star star told Radar.

As Bravo fans may remember, Scheana got off to a bad start with Glanville after she admitted to being one of Eddie Cibrian’s mistresses years ago.

Although she’s hoping for a drama-free wedding at the Humming bird Nest in the Santa Susana Mountains on July 27, tensions are sure to flare – considering Scheana rescinded Stassi Schroeder’s offer to be a bridesmaid!

“Immediately after I offered it to her, I regretted it. She isn’t someone I even want to associate myself with anymore. I’m done trying to be her friend. I’ve been there for her, but she hasn’t been there for me. She doesn’t deserve my friendship,” she ranted.

“She is invited to the wedding, but I don’t want her in my wedding.”

Bridesmaid drama aside, Scheana revealed that she’ll be walking down the aisle in a custom-made wedding dress, designed by her aunt. The bubbly reality star described the gown as a “mermaid gown with a sweetheart neckline and a chiffon, ruffled train.”

As she works on every last detail, Scheana hopes to say “I do” on Bravo, but says it ultimately depends on whether or not Vanderpump Rules gets picked up for a third season.
