Any news story involving the words "George," "Clooney," and "wedding" is sure to set off alarm bells — and countless Google Alerts! But stand down, ladies and gents: It's just a false alarm this time.

People reports the Gravity actor — who turns 53 today, May 6! — did attend a wedding with his fiancée, Amal Alamuddin, but the nuptials were not theirs.

George and Amal jetted down to Cabo San Lucas, Mexico, to bear witness to the wedding of his longtime friend Thom Mathews.

Though not quite the A-list heartthrob that his friend George is, Thom is a hot actor in his own right. Best known for his roles in the Return of the Living of the Dead and Friday the 13th series, Thom has also shared the screen with George on four different occasions — in an episode of ER, in the TV movie Fail Safe, and in the films Waiting For Woody and The Peacekeeper.

Thom is now president of a Los Angeles construction company called Hammer & Trowel Builders — and was apparently responsible for the remodeling of Sharon and Ozzy Osbourne's house in The Osbournes!

OK, so this was just a warm-up to George and Amal's big event, right? Let's keep those wedding bells ringing!
