Gary Collins Begins House Arrest

We've just learned Gary Collins was booked today in Santa Barbara County, Cal. and is now under house arrest.

Gary was busted back in January for driving a motor home drunk in Santa Barbara -- so drunk that his BAC was an astounding .29, which is more than 3 times the legal limit.

Collins has been sentenced to 120 days, but could only serve 72 days if he abides by the rules.
