'One Day at a Time' star Mackenzie Phillips in drug bust!

The former One Day at a Time star and supposedly recovering addict was busted at Los Angeles International Airport on cocaine and heroin possession Wednesday morning, according to TMZ.com. Officers responded to a call at Terminal 4 where the 48-year-old Phillips was being screened by TSA. During the screening, TSA recovered baggies and balloons believed to be filled with cocaine and heroin.

Phillips is currently in custody. The actress, who has battled drugs since her sitcom days in the seventies, is the daughter of Mamas and Papas founder and singer John Phillips and was once the step-daughter of Michelle Phillips. Phillips' One Day at a Time co-star Valerie Bertinelli also battled cocaine addiction in the early eighties but has since gone on to become a Jenny Craig spokeswoman, pen a book, and land her own sitcom to air this fall.
