Jessica Simpson will have a baby boy, according to new reports.

The 32-year-old singer announced her pregnancy with fiancé Eric Johnson on Christmas Day, and it looks like eight-month-old daughter Maxwell will be welcoming a brother into the family.

An insider told RadarOnline.com: ''It's Jessica's dream come true, she prayed she was having a boy.

''She found out this week after a check-up at the doctor, who asked her if she wanted to know the sex of the baby.

''Jessica immediately said yes and when the doctor told her it was a boy she screamed with joy.

''She was so happy that Maxwell is getting a little brother because that's something she always wanted when she was growing up.

''Jessica and Eric are so excited and have started going through names, but they haven't settled on one just yet.

''It's just a pity their favourite boys name went to their daughter first!''

The 'With You' hitmaker recently revealed her second pregnancy has postponed her wedding plans with Eric, who she starting dating in May 2010 before they got engaged later that year.

She told 'The Tonight Show': ''Apparently it was a part of God's plan for my life ... We've had two different wedding dates, but he keeps knocking me up.

''We're doing it very backwards, I know ... I'll just keep my legs crossed, I guess, this time.''
