Lindsay Lohan’s mom Dina was busted Saturday night outside her Long Island home, a source told The Post.

Dina, 57, was driving a 2016 Mercedes around 7 p.m. Saturday when she allegedly struck another car outside an Outback steakhouse and then fled the scene, TMZ reported.

The driver of the other vehicle reportedly followed Dina back to her home, where she refused to submit to field sobriety tests.

The actress’ mom, however, appeared to be under the influence and was arrested on a DWI charge, TMZ reported.

She’s awaiting arraignment Sunday morning in Hempstead court.

The “Celebrity Big Brother” star previously was arrested in 2013 for driving 77 miles per hour with a blood-alcohol level more than twice the legal limit. She pleaded guilty to a charge of driving while intoxicated and was ordered to complete 100 hours of community service.
