'Buffy the Vampire Slayer' star Sarah Michelle Gellar has married boyfriend Freddie Prinze Jr in Mexico.

A spokesperson said that the couple, who appeared together in this summer's 'Scooby-Doo' movie, married on Sunday in a top secret ceremony.

Gellar and Prinze Jr met while they were working on the teen horror 'I Know What You Did Last Summer' in 1997.

Gellar announced their engagement at her 24th birthday party in April 2001.

Both are set to star in the 'Scooby-Doo' sequel.
