Vicki's Revenge! Gunvalson Plots With Bravo To Bring Gretchen Rossi Back To 'RHOC'

Real Housewives of Orange County star Vicki Gunvalson is going to a whole new level to win her battle against Tamra Judge! As Gunvalson and her nemesis continue to battle it out over social media, RadarOnline.com has exclusively learned from a production source that she's secretly been talking with Andy Cohen about bringing Gretchen Rossi back "to take Tamra down!" Click through 7 photos of Gunvalson and her new secret weapon to find out if Rossi is going to return once and for all!

This past weekend, Gunvalson, 54, shocked her fans by posting a photo of her hanging out with fellow Season 11 newbie, Kelly Dodd, and former RHOC star, Rossi, 37! "Vicki and Gretchen had a total blast hanging out and all the girls laughed their butts off," said the source.

According to the insider, "While the ladies were at lunch, Vicki busted out her phone and texted Andy Cohen to tell him to bring back Gretchen and Lizzie Rovsek. After Andy didn't respond, Vicki called him to tell him that she thought having them both come back would be awesome!"

However, it seems that Gunvalson might have another motive behind her new-found friendship with Rossi and Dodd – as ALL of the three ladies are mortal enemies of Gunvalson's nemesis, Judge, 48. "Vicki is not stupid," said the source. "She knew that posting a photo of herself with Gretchen would absolutely drive Tamra mad!"

As RadarOnline.com reported, Rossi has so far declined offers to return to RHOC, because of ongoing tensions with Judge. "Gretchen is not desperate at all to be back on the show. But, if she did return next season, it would be a lot easier for her knowing that Vicki and Kelly have her back!" the insider told RadarOnline.com. "But, honestly, Gretchen does not need that in her life right now. She is doing so incredibly well without all that drama!"

After hanging out with Gunvalson, Rossi posted a video of herself partying with Dodd on what looks to be a yacht! "What is really happening now is that Gretchen and Kelly have totally hit it off. They've been spending a lot of time together recently," the source told RadarOnline.com.
