AceShowbiz - Actor Christian Slater is eager to become a father again.

The Mr. Robot star is already a dad to two teenage kids from his first marriage, but Christian, who turns 49 on Saturday, August 18, reveals he and his second wife Brittany Lopez are actively trying to start a family of their own.

"I have two (children), so far...," he teased on breakfast show Today on Monday, August 13, as he discussed his family life. "You know, we'll see what happens. We're working on introducing new humans."

The couple wed in December, 2013 after three years of dating, and Christian insists they are still enjoying their honeymoon period, because they are so well-matched.

"She's incredible," he gushed. "It's weird, to be in a relationship as long as we have so far, it's been eight years and I'm still nuts about her. It's great."

Christian credits plenty of communication for their strong marriage, but admits maturity on his part has also played a key role in its continued success.

"We talk a lot. She's one of the clearest communicators that I've ever been around, so that makes things very clear," he shared. "I needed that. I needed clarity and I needed direction, and I needed guidance and a willingness to listen, that's another key element. I'm trying."

Meanwhile, the actor maintains a good relationship with his ex, Ryan Haddon, and spent the weekend at her New York home to celebrate their daughter Eliana's birthday a few days early.

"My daughter just turned 17... Her actual birthday is tomorrow, but this weekend we celebrated it upstate at her mum's house and we had a really nice time. It was good."

The former couple also shares son Jaden, who was born in 1999.

Christian and Ryan, the daughter of former model Dayle Haddon, separated in late 2004 after four years as husband and wife. Their divorce was finalised in 2006.
