The actor came to the aid of a group of teenage girls who were stranded in a parking lot in Sherman Oaks, and editors at TMZ.com report that Matt stopped to help the group and offered to fix their vehicle so they could continue their journey.

Pictures posted online show him changing the tyre, and he also posed for a snap with the group when he was finished.

Matt is best known for his role in teen TV show 90210, in which he played a bad boy bartender, and he also starred in 2008 parody film Disaster Movie. He appeared in another parody project, Vampires Suck, in which he played a character who spoofed Robert Pattinson in the Twilight Saga.
