Charlie Sheen On Welcoming Twin Boys: "It's Pretty Amazing"

Although they're not identical, Charlie Sheen and Brooke Mueller's newborn fraternal twin boys are still managing to fool their dad.

"I can't tell! They're not identical, but at this stage they're similar enough." Sheen, 43, told Entertainment Tonight from the set of Two and a Half Men just days after wife Brooke Mueller Sheen, 31, delivered twin sons Max and Bob. Charlie said he likes short and sweet names: "[Their names] are very short and simple – easy to spell and remember," Sheen said. "Bob is the same frontward and backward. I'm a fan of a short and simple name. Max was literally Nick until about a minute before he came out."

Charlie went on to say that life at their LA home is tiring yet phenomenal. "It's pretty amazing. Not a whole lot of sleep, but what parent does at this stage? There's adrenaline, excitement, fear."

And big sisters Lola, 3, and Sam, 5, Sheen's daughters with ex Denise Richards, are super excited as well: "[They're] thrilled," he said, "but insisting that they're named Bob and Duke. It's not Max, it's Duke."

Charlie now has five children. Sheen and ex-girlfriend Paula Profit have a 24-year-old daughter, Cassandra Jade Estevez.
