Lindsay Lohan and Patrick Aufdenkamp stroll through the Malibu Lumber Yard on Saturday afternoon.

The starlet looked great in tiny cut-off shorts and combat boots.

Lindsay has been bright and smiley since being released from rehab in early January.

According to her father, Michael Lohan, Lindsay reportedly skipped her grandmother’s 87th birthday two weeks ago to focus on her sobriety.

Since leaving the Betty Ford Center, Lindsay has passed nearly 10 random drug and alcohol tests. Keep it up, Lindsay!
