“REAL Housewives of Orange County” beauty TAMRA BARNEY reveals she’s booted her co-star ALEXIS B ELLINO from her list of wedding guests.

And in an exclusive ENQUIRER interview, Tamra adds that Alexis may not be the only familiar face absent when she walks the aisle with Eddie Judge in June. “Let’s just say not all the Housewives will be invited,” declared feisty Tamra.

When asked about Vicki Gunvalson, Tamra replied: “Um, maybe.” But when the subject of inviting Alexis was broached, the 45-year-old blonde snapped: “No!”

Tamra and Alexis have butted heads many times in the past. Last season, fitness studio owner Tamra called her surgically endowed rival “Jesus Jugs.”

And a shocking incident occurred on the April 22 show when Vicki brought Alexis to a dinner party celebrating the opening of Tamra’s new gym. Alexis called the fitness buff a bully, and Tamra went through the roof and ordered her to “get the **** out!”

“Vicki had been trying to smooth things over,” said a source close to Tamra and Eddie. “She was hoping to broker an end to the feud so that Tamra would invite Alexis to the wedding.

“But Alexis just couldn’t resist taking another shot at Tamra – and that ended any chance of getting all the ‘Housewives’ together.

“Both Tamra and Eddie want nothing to do with Alexis.”

Meanwhile, the happy pair are staying focused on their big day. They held joint bachelorette and bachelor celebrations May 18 in Las Vegas. Guests first made waves at The Palazzo’s Azure Luxury Pool, then they dined and did some gambling before finishing up at a strip club. The bride- and groom-to-be were joined by “RHOOC” co-stars Heather and Terry Dubrow. But “Housewives” Gretchen Rossi, Alexis, Vicki and Lydia McLaughlin were noticeably missing.

Said the source: “This wed­ding may be tearing the cast apart – and Tamra loves it.”
