Real Housewives of Beverly Hills star, Kim Richards, is breaking her silence on the death of her ex-husband, Monty Brinson, who lost his battle with cancer this past weekend.

As we previously reported, Richards’ brother-in-law, Rick Hilton, confirmed the news on Instagram Sunday. “His heart was a big as the moon and he was loved by all he Met,” he wrote.

On Monday, Richards took to Instagram to post a photo of herself dancing with Brinson, with whom she shares 29-year-old daughter Brooke. She has taken care of him in recent years as his health deteriorated.

“Yesterday I said goodbye to best the friend I've ever had in my life,” she wrote. “Monty was an amazing person with an amazing soul ... We shared over 30 years of Love & Happiness and brought a beautiful daughter into world. I am so grateful for all that we shared. I know we will be together again one day.”

“I will carry you in my heart always my love,” she continued, “until then may you rest in peace.”
