Anna Faris is expecting a baby boy

The 35-year-old actress and husband Chris Pratt - who married in July 2009 - are ''very excited'' about the impending new arrival and can't wait to be parents to a son.

A source who revealed the baby's gender to Life & Style magazine said: ''She's very excited about it.

''She's six months along and everything is going great, just as planned.

''They're both happy and are really looking forward to being parents.''

Anna previously admitted her mother had been desperate for the 'Dictator' star to give her a grandchild for some time.

She said: ''Chris and I both want a family. Mom has been saying to me for some time, 'You had better start soon.' ''

Anna - who was previously married for three years to Ben Indra, before divorcing in 2008 - and Chris were only engaged for six months before getting married but the actress believes it was meant to be as they lives had so many similarities.

She explained: ''When I fell in love with Chris it was great. We both grew up in little towns next to each other near Seattle and I found that very comforting.

''My marriage didn't work out the first time round but I am still a big believer in marriage.

''We lead a boring life in LA on purpose. I never go out, I never go to premieres, don't go to parties and don't live a Hollywood lifestyle.

''My perfect night in is cooking dinner, drinking wine and watching movies - there is nothing I love more.''
