Monty Brinson, ex-husband of Real Housewives of Beverly Hills star Kim Richards, is battling cancer and, on Friday, his daughter, Brooke Wiederhorn, posted a sweet flashback photo of the father-daughter dance at her wedding.
"The best hugs," she captioned the photo, adding a blue heart emoji.

Wiederhorn tied the know with husband Thayer Wiederhorn in two ceremonies. The first took place in August 2014 so Brinson, who had already been diagnosed with cancer, could walk her down the aisle. The second celebration took place in Cabo San Lucas, Mexico, last May. At the time, Richards was able to briefly leave rehab to attend her daughter's nuptials.
On Saturday, Brinson posted his own Instagram, saying that he is "doing great." "Grasp [your day] and enjoy it otherwise all you will be doing is wasting another day," he told his followers.
"Think of everything thrown at me, I've beat so far because I've never given up," Brinson added. "I'm a fighter, not just for me but everyone else who doesn't have the strength, I'm there in spirit to give you strength."
