It's all about the little things for newlywed Jessica Biel
star, 30, who tied the knot last month, says a huge perk of being married
to Justin Timberlake
is getting to use a certain seven-letter word.
"It's weird because it feels like almost nothing has changed, yet something that you can't really describe, or something that isn't tangible has changed," Biel says on The Ellen DeGeneres Show
airing on Monday. "The weirdest and kind of most wonderful thing is that word. That's my husband
Changing up her voice, the actress adds, "That's the word, and every time I say it, I go really Southern with it. 'Oh, that's my husband
. That's him over there.' I touch my hair and I completely go like I'm from the South or something. It's weird."
As for life as Timberlake's wife
, Biel says with a smile, "It just feels incredible. It feels like you have this partner who is going to be with you and also change light bulbs and do dishes with you."
