(Cover) - EN Showbiz - Jennifer Garner feels absolutely privileged to be the age of 40.

The stunning actress shares three children Violet, six, Seraphina, three, and Samuel, six months with actor Ben Affleck.

Jennifer turned 40 in April and husband Ben celebrates his entry into his forties today.

The star isn't convinced that Ben is as happy as entering the new epoch as she was initially.

"I like being 40," she said on US talk show Late Night with David Letterman.

"I don't know that he's as thrilled with the idea of 40 as I am. I really like it. I had no problem with it. I feel like, what more could I want? I can't speak for him, but it doesn't look he's as happy as I am about turning 40."

When asked by host David whether or not Ben was complaining about his new age, Jennifer made it clear that the actor is far from whiny.

"Are you asking about Ben Affleck's testosterone level? Really, David! He will thump you," she laughed.

"Have you seen my husband lately? He is walking testosterone." (C) Cover Media
