Sarah Michelle Gellar will celebrate her 39th birthday Thursday, April 14, 2016. Best known to fans as television's popular "Buffy The Vampire Slayer," Gellar also won major accord for her negative role in "Cruel Intentions."

After Buffy, Gellar was seen in various films in the horror genre including "The Grudge" and "The Grudge 2." She then bagged the role of Daphne in live-action "Scooby-Doo" films.

Not just her professional life, Gellar seems to have a rocking, happy and content personal life too. The actress has been married to Freddie Prinze Jr. since 2002, who was also her co-star in "Scooby-Doo" films, and has three children with him.

On her birthday, we decided to bring to you some of the most adorable photos of Gellar with her husband.

Though her fans still remember her as the face of Joss Whedon's beloved vampire-hunting series for seven years, the actress is now all set to make a comeback to television to reprise her role as Kathryn Merteuil in "Cruel Intentions" TV spin-off.

The spin-off of this 90s cult hit is set to debut on TV sometime later this year, and the actress confirmed the same by posting some behind-the-scenes photos from the sets of the show.
