It's going to be a boy for Carrie Prejean!

Pregnant with her first child (the dad is husband Kyle Boller), the controversial beauty queen will have a son, her attorney told Radar.

"Carrie is really happy about having a boy and becoming a mother," lawyer Charles LiMandri said.

The baby's due date is May 9, 2011.

Prejean, 23, wed pro footballer Boller in July.

After the pregnancy announcement, Boller gushed: "I have the most beautiful pregnant wife ever, we are so in love and this was just the best news when we found out a couple of weeks ago."
