Sarah Michelle Gellar and Freddie Prinze Jr. should expect to receive plenty of blue gifts for their impending arrival.
According to People magazine, the two are expecting a little boy.
After ten years of marriage, Gellar and Prinze already have a little girl who is now close to three years old.
A source close to the couple told the magazine they're over the moon about the new addition.
“They are thrilled that Charlotte will have a little brother,” the source said. “They love their little girl more than anything in the world and know that love will only multiply."
The 35-year-old former "Buffy the Vampire Slayer" star tied the knot with 36-year-old Prinze in Mexico in September 2002.
While Charlotte turns 3 in September, it's not yet known when the couple's newest baby will be born.
