(Anstead also has two older kids, daughter Amelie, 17, and son Archie, 15, with his ex-wife.)

Despite no longer being with Haack, Anstead says he still considers El Moussa and Young like family, because of their connection through the kids.
“I’m a big supporter of modern-day parenting. I’m a big supporter of modern families,” Anstead tells PEOPLE exclusively, explaining that he still thinks of Taylor and Brayden as his stepchildren.

“To treat them in any other way would be dishonorable,” he continues of their mutual respect and support. “I’m really proud of how we all kind of manage that modern blend.”
“I think it was really nice that they attended the event because ultimately that speaks volumes,” Anstead said. (The black tie affair also happened to be his first public event with new love Renée Zellweger, whom he began dating in June after meeting on the set ofCelebrity IOU: Joyride.)

Anstead and the Academy Award-winning actress, 52, have been very private about their relationship since it began, but have been spotted spending time together with Hudson, hanging out at Anstead’s home in Laguna Beach, walking along the beach and attending open-air church services.
“They are getting pretty serious about each other,” a source close to the couple told PEOPLE last month. “They’re both busy with various projects and their careers, but they have a major attraction to each other.”

“Sometimes two people just meet and click, and the timing is right,” the insider said at the time. “Renée is creative … and oftengoes for guys who think out of the box. She’s smart, thoughtful and always looking to expand horizons and nurture those around her.”
“Both of them are private and dislike public scrutiny, so they have that in common. He’s a creative guy with lots of interests, and she likes to write and produce, so they have things to talk about when together,” they added.
