Although neither party has confirmed any such thing as of yet, Brinson certainly teased of the possibility in a new Instagram post.

"Sitting in bed early in the morning, just thinking how wonderful yesterday was with @kimrichards11," Brinson wrote on Sunday, along with a photo of himself and his ex-wife -- kissing. "What makes me laugh is people wondering are we or are we not. All I can say is I'm so proud of Kim and can't wait till the premier of your movie this month and for the world to see how beautiful and great you are doing and committed you are for yourself in finding the happiness you deserve and staying on track with your life."

Although Richards and Brinson have been divorced for many years, they have remained close, and during filming on The Real Housewives of Beverly Hills season five, it was revealed they were living together.

"There are so many people out there pulling for you and just remember you are loved by many," he continued ."Always stay strong and don't let people walk over you or take advantage of you anymore. Spread the love. I'm proud of you and blessed to know you...We are all in this together and you're never alone and your family loves you so much."
