The model -- whose husband left her after he was caught cheating with LeAnn Rimes in 2009 -- was reportedly pulled over on Sunset Blvd. for an unknown traffic violation at 12:05 in the morning.
According to TMZ, law enforcement sources say officers detected the smell of alcohol and Glanville, 36, was given a field sobriety test. She was then arrested for suspicion of DUI.
The model (and mom to Mason, 7, and Jake, 3) left the Beverly Hills police station at 8:21 Thursday morning, Perez Hilton reports.
Glanville addressed the incident on her official Twitter account Friday afternoon.
"I messed up. I take full responsibility for my actions," she tweeted. "I regret my bad choice, and am thankful to God that no one got hurt. I'm sorry.
