Ryan Reynolds may be his daughter James’ No. 1 fan — but baby James seems to prefer mom Blake Lively instead!

“[It’s] all about mom. I am dead to her, literally dead to her. That’s her first words, ironically,” the 38-year-old actor joked about his seven-month-old daughter during an interview on Conan on Tuesday, Aug. 4.

“Right now, she’s starting to say ‘Mama,’ but there’s an unfair advantage there — it turns out breasts are actually a life support system and the child seems to gravitate towards the breasts. I’m just the breastless a–hole wandering around the room and getting in her sight line every once in a while,” he continued.

The actor also opened up about the day his wife went into labor last winter — and revealed Blake was quite the jokester in the delivery room!

“My wife is the real, I mean she is a mercenary. At one point in the middle of the delivery, the doctor’s cell phone went off and she said, ‘Oh, no. Go ahead, take a personal call. Feel free.’ She was cracking jokes in the delivery room. She may have been on drugs, but I don’t ask personal questions,” he said.
