Ryan Reynolds has joked that he and Blake Lively's baby daughter is "allergic to sleep".

The Hollywood couple welcomed their first child, whose name is still unknown, at the end of last year.

During an appearance on The Tonight Show last night (March 3), Reynolds said: "Our baby in particular is, we think, allergic to sleep... We think that she thinks she's protecting us from the sleep monsters. Like, 'Oh, I've got to keep them up or the sleep monsters will get them'. God."

The Deadpool star also admitted that his daughter has him "wrapped around her little finger".

He said that fatherhood was "the best", adding: "I am a slave to the rhythm... I can't wait. It's just going to be teatime every day with her."
