Jessica Biel is already thinking about having a baby.

The 'Hitchcock' actress - who married 'Cry Me A River' singer Justin Timberlake, 31, in front of more than 100 close friends and family at the plush Borgo Egnazia resort in Puglia, Southern Italy, on October 19 - revealed she fell in love with her young co-star Noah Lomax on the set of their new movie 'Playing for Keeps' and has already discussed having a baby with her new husband.

When asked if playing a mum had made her think about having her own children, he 30-year-old actress said: ''Yeah, sure. I think especially because the kid, Noah [Lomax], who plays my son [in the movie], is literally the coolest kid I've ever met.''

The brunette beauty also opened up about being married to the 'SexyBack' singer and admitted it feels ''amazing''.

She told 'Good Morning America': ''It feels like nothing's changed, and yet, everything's changed.

''It's like that intangible thing, you can't quite put your finger on it. But I guess the idea of having a sort-of partner in crime, and the word 'husband,' is pretty amazing.''

The couple are planning to enjoy a traditional first Christmas together later this month.

She said: ''I think we're pretty much going to do the same things we do every year: hang out with our family and be very mellow.''
