Former "One Day at a Time" star Mackenzie Phillips has had a difficult few years, between a stint on Vh1's "Celebrity Rehab" and being in the media spotlight over an alleged sexual relationship with her famous father. But she’s intent on moving forward.

In her latest effort, Phillips is getting somewhat of a makeover thanks to OWN's "Extreme Clutter." On Part 2 of the show's Season 2 premiere, which airs Jan. 2, organization expert Peter Walsh visits the actress to help her gain control of her home. It's crowded with material representations of painful memories that stem from years of substance abuse and emotional family upheaval.

"I think it's the last vestige of the junkie I used to be," Phillips says of her cluttered home in this exclusive video interview. "But why am I hanging onto the past?"

Phillips's home doesn’t appear particularly overloaded with objects. "It's not like 'Hoarders,'" she explains, noting that her problem is "hidden clutter." In sorting through her things, Phillips picks up a doll from her father, John of The Mamas and The Papas, and boots from her actress/model sister, Bijou.

Walsh notes that the actress's house is "filled with disturbing reminders of her days as a drug addict." Throughout the series, Walsh helps people whose lives have been dramatically affected by overwhelming clutter. He guides families through the emotional journey of overcoming their attachment to material items by pinpointing the root of their problems and guiding them towards a clutter-free life.

And seemingly, it works with Phillips. "You let go of the things that have negative power and keep the things that fit into your future," she says about what she's learned at the end of the interview.

"Extreme Clutter" will have a two-night premiere beginning Sun., Jan. 1 at 11 p.m. EST on OWN and then Mon., Jan. 2 in its regular time slot at 10 p.m. EST with Mackenzie Phillips's episode.
