Hollywood actress Demi Moore and her actor boyfriend Ashton Kutcher are shunning parties to stay at home because they are trying for a baby, reports the Internet Movie Database.

The 42-year-old "Ghost" star - who already has three children with former husband Bruce Willis - is desperate to expand her family with her 27-year-old lover, reports the New York Daily News.

"We truly desire to expand our family," said the actress who has been dating Kutcher since May 2003.
