The Hollywood actress already has two children, Ava, 12, and eight-year-old Deacon, with her first husband Ryan Phillippe but she would "love" to have a baby with her talent agent spouse Jim Toth, who she married last year.
When asked if she would like to have another child, she said: "I`d love that. I feel really good and I`m at a really good place in my life."
During one scene in the 35-year-old beauty`s latest movie `This Means War`, the 35-year-old beauty has to sing and dance around the kitchen - and Reese admits she often "embarrasses" her children when she does just that around the her own home.
She told LOOK magazine: "It`s usually country music and my kids just plug their ears and pray for the song to end!
"The other day I was dancing around the house when they came in and literally stared at me like, `Oh my God, that`s so embarrassing.` But I didn`t stop. You can`t stop dancing."
Reese wasn`t nervous about the scenes in which she has to kiss Chris Pine and Tom Hardy in the movie and instead found it to be one of the most fun days on set.
She added: "It was a lot of fun making out with two very handsome guys. A girl couldn`t ask for more than that."
