Denise Richards and Aaron Phypers have split after six years of marriage

Aaron cited "irreconcilable differences" as the reason for their split, and the date of their separation is listed as July 4.

In the court documents, the actor lists Denise's youngest daughter - 14-year-old Eloise, whom she adopted - as his stepchild, and he's asking the court to award him spousal support.

Aaron also claims that he's earned zero dollars over the past 12 months, after shutting down his business. On the other hand, he claims that Denise - who also has daughters Sami, 21, and Lola, 19, with ex-husband Charlie Sheen - has a monthly income of $250,000.

The actress was married to Charlie between 2001 and 2006, and she previously insisted that she wouldn't get divorced ever again.

On an episode of the reality show Denise Richards and Her Wild Things, she said: "I'm never getting divorced again. Even if we hate each other, I'm not gonna f****** get divorced."

Prior to that, Denise admitted that her break-up from Charlie was "really hard" on her career.

She told Us Weekly: "That was really hard for my career.

"A lot of people didn't want to hire me. That has been a roller-coaster of a journey, and he's been one of my biggest teachers of learning a lot about myself actually!"

Denise also revealed that Charlie has totally different style of parenting.

The Hollywood star said on the Whine Down with Jenna Kramer podcast: "I parent my way. He parents his way, and there was no co-parenting."

Denise regrets that she doesn't have a better relationship with her ex-husband.

She said: "I have kids with him, and I'm not really - I'm friendly with Charlie, but I wish we were friends."

Denise hopes that their relationship will improve over time. What's more, the actress wants to avoid a scenario whereby her children have to picks sides between herself and Charlie.

She said: "I just didn't want the girls to feel like they had to choose sides."
