Freddie and Sarah welcomed their first child – a daughter named Charlotte Grace Prinze — on Sat., Sept. 19, a rep for the former Buffy The Vampire Slayer star told PEOPLE on Tuesday

It is the first child for the couple, who first met in 1997 while filming I Know What You Did Last Summer. They wed in 2002. Freddie and Sarah — who recently changed her surname to Gellar — are said to be “over the moon” about their daughter’s birth.

Freddie Prinze Jr. and Sarah Michelle Gellar will be welcoming the arrival of a baby girl later this year. The couple recently announced that they are expecting their first child together after seven years of marriage.

According to Star, 32-year-old Sarah, who is five months pregnant, has been overheard excitedly talking about her unborn daughter on the New York City set of her new HBO pilot, The Wonderful Mondays.

“She’s been letting little details slip here and there,” says a set source. “She’s been spending her free time planning the nursery in their TriBeca apartment,” according to gossips. “Sarah wants the room to look sophisticated, so nothing too frilly or princessy. She’s been shopping for earth tones to mix with plum or magenta accents.”

A source close to the couple has revealed that the former Buffy the Vampire Slayer star and her husband of six years will welcome a bouncing bundle of joy this fall.

“They’re very excited,” says the source..

The mother-to-be turns 32 next week. Freddie, 33, is reportedly set to star in a new comedy for ABC.

Congrats.

Actress Sarah Michelle Gellar is reportedly in negotiations to star in a new big screen adaptation of her small screen cult classic, Buffy The Vampire Slayer.

“There is an idea for a script and to pick the story up with Buffy older and maybe even a mother,” Britain’s Daily Star reported on Tuesday. “Michelle is busy with movie projects at the moment but she is excited about the idea. Buffy still has a huge fan base so this is a movie that already has an audience.”

The 31-year-old actress ended her seven-year run as Buffy– based on Kristy Swanson’s 1992 comedy–in 2003.

These shots were taken on June 11th and June 13th.

Sarah Michelle Gellar appeared on Rachael Ray on Monday.
