She said she enjoys helping Sheen care for the boys while mom Mueller is not around. "I love those boys. I would take a bullet for them," she said.
Despite his love for his children, Sheen said he was not worried about his kids' being negatively affected by his lifestyle choices or recent headline-making actions.
"I'm not going worry about it, or I can say, 'Hey, kids, your dad's a rockstar. Look at his experiences. Look at what he survived.' Bang. There are some of your lessons, but the real lessons are going to be in the future," Sheen said.
Sheen is a father to five children -- 26-year old daughter Cassandra, who was recently married, and four kids who are minors, including two daughters, Sam and Lola, who are in the custody of ex-wife Denise Richards.
Sheen said he doesn't spend enough time with his daughters, who are 5 and 6, to have his more controversial behaviors, such a highly publicized weekend bender, have an impact on them.
"I don't see them enough to have that influence, but that was yesterday and today it could be different. I don't know," he said. "They'll wake up one day and realize how cool dad is. And, you know, signs all the checks on the front, not the back. And you know, we need him and we need his wisdom and his bitchin'-ness."
