TV host Pat O’Brien is the latest celebrity to check into rehab, following hot on the heels of Amy Winehouse, Kirsten Dunst and Eva Mendes. The 59-year-old host of "The Insider" has checked into a facility for unspecified treatment.

A statement from show producers confirms, "O'Brien and his doctors felt this is the best course for maintaining his sobriety."

O'Brien made headlines in 2005 when he spent time in rehab for alcoholism, after lewd voicemail messages he had left a female acquaintance were leaked online.
