Hot in Orange County!
Real Housewives of Orange County Vicki Gunvalson, Tamra Barney and Gretchen Rossi visited the set of Hot in Cleveland on Friday in support of castmate Heather Dubrow’s guest role.
Joined by fiancé Eddie Judge, Barney arrived at 5 p.m. with Gunvalson but Rossi and boyfriend Slade Smiley were an hour late.
“The ladies seemed to be having a good time in the audience greeting fans,” an onlooker tells PEOPLE. “Tamra even got up to dance with a fellow audience member between takes.”
And although they may feud on the Bravo reality show, the women couldn’t have been more supportive of Dubrow.
“All the girls cheered and clapped for Heather every time she was on set,” the source says.
When the taping ended, the Housewives came down to the stage to greet the cast and pose for pictures on set.
“They were overheard saying they were all going to dinner to celebrate Heather’s guest role,” the source adds.
