For Josh Duhamel
, it's all about the boy.
In Austin, Texas on Saturday night for the G. H. Mumm
Art of Celebration Formula 1
event, Duhmel, 40, proudly showed off pictures of his 3-month-old son, Axl
with wife Fergie
"He was all about baby Axl, showing party guests iphone photos of him," says an observer at the party. "He was saying fatherhood is the best experience and that he is having the best time with him. He said everything is all about the little man now. He was just an adoring father."
Duhamel also learned how to "sabrage" a champagne bottle – using a saber along the body of the bottle to break the neck – on his first try. Along with lots of champagne, the party also featured aerial performers who hung from red ribbon, pouring glasses of champagne for party guests while a DJ spun a variety of tunes.
