Sarah Michelle Gellar and husband Freddie Prinze Jr. welcomed a baby boy back in September, and they're just now revealing his name: Rocky James Prinze!

Gellar, 35, and Prinze, 36, who were married in September 2002, also have a three-year-old daughter, Charlotte Grace.

“They are thrilled that Charlotte [has] a little brother,” a source close to the couple told People back in July.

“They love their little girl more than anything in the world and know that love will only multiply.”

Buffy finally had her baby!

Sarah Michelle Gellar gave birth to a son in Los Angeles last week, her rep confirmed to Us Weekly.

"Sarah Michelle and Freddie Prinze Jr. and thrilled to announce that they welcomed a baby son into the world this past week. Mother and baby are doing great. And Charlotte is VERY excited to be a big sister," the rep said in a statement.

The Ringer actress confirmed she was expecting in April, and in July reports of the baby's sex surfaced.

The infant's name has yet to be released.

Congrats to the happy family on their new addition!

A heavily-pregnant Sarah Michelle Gellar, 35, took daughter Charlotte and a friend to ballet Saturday. And if Sarah and hubby Freddie Prinze's first child is any indication, their second will be super adorable too!

Gellar and Prinze announced they're expecting a baby boy -- her pregnancy was announced in April, so we're guessing she has an October due date. Wonder what the former Vampire Slayer will name baby #2?

Break out the blue!

Sarah Michelle Gellar and husband Freddie Prinze Jr. are expecting a son, Us Weekly reports. "She and Freddie are thrilled. They're amazing parents," the source revealed.

Although The Ringer star and her She's All That actor hubby grew up in showbiz, their focus is now all about family. "They still have date nights all the time and have a normal life. They both came of age in Hollywood and love working, but their home life is more important to them," the source adds.

Their upcoming arrival will join big sister Charlotte Grace, 3.

Congrats to the happy parents!

Even with one in the oven, Sarah Michelle Gellar's mommy duties are never at a halt!

Over the weekend, the 35-year-old actress was seen picking up her adorable two-year-old daughter Charlotte and one of her friends from ballet class in Sherman Oaks.

At five months pregnant, the Buffy the Vampire Slayer star is doing her best to help pick up the slack while her husband Freddie Prinze Jr. remains out of town for a film shoot with actress Mena Suvari. We're hoping she'll at least let us know if it's a boy or a girl!

When you have a child this cute, why not have another one?!

Pregnant actress Sarah Michelle Gellar took her adorable daughter Charlotte Grace shopping at the Brentwood Country Mart on Saturday, and although the 35-year-old and her husband Freddie Prinze Jr. announced they were expecting last month, we still can't spot much of a baby bump!

Being a working mom in Hollywood is a project in multitasking, but Mrs. Prinze Jr. will have a lot more time to spend with her baby after she gives birth this time around, since her show The Ringer was axed due to poor ratings earlier this year.

Her hubby, on the other hand, hasn't worked for ages, but seems to be stepping in to pick up the slack now that Miss Gellar is on mommy duty. The She's All That actor is currently filming a still untitled movie with Mena Suvari.

A family that juggles responsibilities together stays together!

Her new CW series The Ringer may have been cancelled after just one season, but Sarah Michelle Gellar is all smiles since announcing she's preg with baby No. 2!

The Buffy star showed off her growing bump as she spent quality time with daughter Charlotte, after picking her up from ballet class in LA, on Saturday afternoon.

Gellar's two-year-old looked adorable in her little ballet leotard, while the actress looked maternity-chic in a loose-fitting top, black tights, ballet flats and an oversized Prada handbag.

Sarah and hubby Freddie Prinze Jr announced last month that they are "thrilled" to be expecting a second child, and she's due at the end of the year!

Sarah Michelle Gellar and Freddie Prinze, Jr.'s family is growing!

The Ringer star has just announced that she is pregnant with her second child, and "She and Freddie are thrilled. They're amazing parents," a source confrims to US Weekly.

The couple met while filming the 1997 horror flick I Know What You Did Last Summer, tied the knot in Mexico on September 1, 2002, and welcomed daughter Charlotte Grace in September 2009.

Prinze has been taking on the role of Mr. Mom recently with little Charlotte, while Geller has been hard at work filming the first season of her hit new show, The Ringer.

The Buffy the Vampire Slayer star recently said of her hubby's new role as a stay-at-home dad, "He loves it. We fight over who gets to stay home. You'd think it would be the opposite, that the parents would be like, 'No, I'll go to work!' but he's like, 'You stayed home for two years! It's my turn! He and Charlotte have too much fun," Gellar added. "I'm jealous!"

Congrats to the happy couple!
