Shayne Lamas was apparently confident she could make it through a mandatory police checkpoint over the weekend, but she was incorrect.

The Leave it to Lamas star and former The Bachelor: London Calling winner was arrested on a suspicion of DUI charge just after 1AM on Saturday in Venice, CA, E! News reported.

"Early Saturday morning, after consuming one drink, I willingly drove through a mandatory check point on my way home with complete confidence of passing," said Lamas in a statement obtained by E! News.

"However, the breathalyzer indicated that I was over the legal limit of blood alcohol content and was arrested onsite."

The 24-year-old was released later in the morning and is due in court on December 9 to face the misdemeanor charge, E! News reported.

"I take full responsibility for my lack of judgment," Lamas told E! News.

"I have always strived to be a role model for my friends, family and fans and have never nor will ever condone drinking and driving. I apologize for all those I have disappointed, including myself."

Lamas received the final rose and a marriage proposal -- both of which she accepted -- from The Bachelor: London Calling star Matt Grant during the show's pre-taped May 2008 finale.

Despite insisting they were in love, the couple eventually called off their engagement that July after a report surfaced that she had cheated on him, which she subsequently denied.

Leave it to Lamas premiered on E! last month and follows her family in their everyday life.
