We love it when our favorite reality stars from different shows hang out together. And that was the case this week, as Real Housewives of Miami star Joanna Krupa palled around with Real Housewives of Orange County's Gretchen Rossi.

We hadn't realized that Gretchen and Joanna were so close, but they both posted a photo on January 20 of themselves posing with Joanna's pal Diana Madison, as the three ladies channel Charlie's Angels.

"Such a fun lunch w the girls! @GretchenRossi @dianamadison #goodballs #beverlyhills," Joanna captions the pic.

Meanwhile, Gretchen captions it, "@joannakrupa @dianamadison & I being silly in Beverly Hills after a fun lunch!! #friends #greatgirls #beingsilly #charliesangels."

All three of the ladies look amazing in this pic, as we love what they're all wearing. And those shoes are totally fab! But above all, it's great that they're capable of having fun and cutting loose. 

Joanna has been hanging out with a number of reality stars from other shows lately. We've seen pics of her with Real Housewives of Beverly Hills stars Joyce Giraud and Lisa Vanderpump, along with Shahs of Sunset star Lilly Ghalichi. Of course, there's one reality star whom Joanna isn't tight with, and that's Brandi Glanville.

Are you surprised that Joanna Krupa and Gretchen Rossi are besties?
