Jessica Simpson is expecting a baby girl, according to the pop star's friends.

The singer and reality TV star has yet to confirm month-old reports suggesting she's pregnant - but pals, it seems, can't keep their mouths closed when it comes to the happy news.

A source close to Simpson and her fiance Eric Johnson tells In Touch magazine, the couple is painting the nursery pink.

A pal tells the publication, "She's telling people it's like winning the lottery, twice."

Simpson and Johnson will reportedly exchange vows in Hawaii on 11 November (11) and the slack-jawed friend also reveals the stars have a couple of names already picked out - Morgan and Karen.

The source says, "She and Eric are both so happy," adding that Johnson has already ordered pink bubblegum cigars to hand out when the baby arrives.
