Cassandra’s mother is the actor’s high school girlfriend Paula Profit.

Charlie and Denise, who were married from 2002 to 2006, have two children together, Sam, 8, and Lola, 7. The actor also has 3-year-old twin sons, Bob and Max, with Brooke Mueller -- who Denise often looks after when needed. 

“They’re our family and they’re Sam and Lola’s brothers and I can’t imagine growing up without my sister, so anytime she needs help, I’m there for the boys,” she said during a visit to "Access Hollywood Live" in December. “[Sam and Lola] are the best big sisters to [the boys] and they love them.”
