The actress, who has 15-month-old daughter Billie with TV star Eric Dane, gushed about her experiences as a first time mom at the Chrysalis Butterfly Ball 10th Anniversary event in Los Angeles.

While it's not always been easy, the 39-year-old is enjoying motherhood.

"It's been amazing. It's challenging, but it's the greatest thing ever," she said.

Rebecca couldn't contain her happiness as she said she would "absolutely" like to have more children with her husband.

The Jawbreaker star praised Eric for being a wonderful father to daughter Billie.

"They have a great time together. He likes to do all of the fun stuff with her," she said.

The proud mom also revealed her daughter has started to talk now. Although Billie's vocabulary is still limited, Rebecca was delighted to reveal her first words.

"Oh my gosh, she is walking now, she is talking now!," she told the American edition of OK! magazine. "She is only 15 months so she has about four words. She says, Mama!', Dada' is one, she says, Ball,' she says Hi,' and she says, Duck!'" (C) Cover Media
