Christine Quinn and Chrishell Stause have been at odds ever since Stause, 39, joined The Oppenheim Group during season 1 of Selling Sunset, but Quinn is still showing her support.When a fan tweeted at Quinn, 31, asking for her reaction to the Wednesday, September 2, announcement that Stause joined Dancing With the Stars, the realtor was quick to share her thoughts.“I’m happy for her! Sounds fun,” Quinn tweeted.
