Marie Claire just wanted to wish everyone a "sparkling, joyful and warm holiday," but the magazine's flack forgot to Bcc, exposing precious celebrity email addresses to 582 people. Christmas is ruined!

Marie Claire's is of course only the latest message to illustrate the perils of forgetting to put addresses on the Bcc: line instead of To:. Fox News' Susan Estrich and Mediabistro's Laurel Touby have similarly embarrassed themselves.

But Marie Claire included some A-listers among the usual stew of New York media people. Their email addresses are now overexposed! Time for new GMail accounts or whatever! Which is easy enough, but reconfiguring iPhones and BlackBerrys could waste literally days, collectively!

A partial list of victims:

• Tina Fey
• Ashley Olsen
• Maggie Gyllenhaal
• Rachel Weisz
• Lindsay Lohan
• Jeremy Piven
• Oliver Platt
• Sandra Oh
• Sean Avery
• Nina Garcia

Keep them in your prayers!
