LOS ANGELES, Calif. – This time, it will be a boy for Jessica Simpson and fiance Eric Johnson.

Simpson revealed on “Jimmy Kimmel Live!” Wednesday that she is expecting a baby boy. She and Johnson are already parents of a daughter, Maxwell, who was born in May.

Simpson announced in December that Maxwell would be a big sister, but she hadn’t revealed the gender of her new baby.

She didn’t plan to reveal it Wednesday, either. She told Kimmel that she hadn’t been feeling well during her second pregnancy, adding, “I never knew a wiener could actually make me nauseous.”

She followed up by saying she “couldn’t believe” she “just told the world” she’s having a boy.
