The couple ' who have been married for almost seven years and have three-year-old twins Max and Emme together ' are unsure whether they will go on to expand their family further, though the 'American Idol' judge admits they have discussed having another baby.

Asked if they are planning more children, she said: ' don't know, we'll see. We'd like to but you never know. We talk about it but we'll see.'

Jennifer ' who was named Most Beautiful Woman in the World by People magazine last month ' also spoke of how much she had enjoyed a lazy day with her family on Sunday (08.05.11), which was Mother's Day in the US.

She told TV talk show host Jay Leno: ' did nothing and I loved it. I stayed in bed, Marc stayed in bed with me. It was so cute, the kids let me sleep in a bit and then about 9.30, there was a knock and they came in shouting 'Happy Mother's Day!' and they both were holding a rose. It was the best moment of the whole day.

'Marc just wrote World's Most Beautiful Mom in my mother's day card, that was all. There were tears.'

Jennifer's decision to pursue a career as a dancer when she was 17 caused tensions between her and her mother and the 41-year-old beauty admits she would expect Max and Emme to 'prove' they were serious if they have similar ambitions when they get older.

She explained: 'f they really want to do it then I can't stop them and I'll have to support them, but if they're experimenting, I'll have to be more cautious and be real 'mom' about it ' like my mom was with me, I had to prove it to her.'
