Teen Mom star Farrah Abraham pled not guilty to her DUI case on Monday.

Abraham, 21, entered a "not guilty" plea for 3 charges- aggravated DUI, refusal to take a field test and disorderly conduct, according to TMZ. Abraham's trial for the DUI case is scheduled to begin on May 31.

The reality star made headlines when she was arrested in the early hours on March 18 in Omaha, Nebraska for driving erratically on the road after celebrating St. Patrick's Day.

Authorities had Abraham take a sobriety test and it failed when it read .147, which is almost twice the legal limit, TMZ reported. The gossip website wrote in another report that Abraham gave local officers difficulty when she was asked to take the Breathalyzer test. She reportedly "put her teeth onto the tube and didn't provide a sufficient sample."

The report also stated that Abraham was "banging her head against the (police car) window while yelling and screaming" when she sat in the back of the police car."

Enstars reported that the mother-of-one finalized a deal with the adult industry's leading film company Vivid Entertainment. Abraham secured a deal with a "high six-figure deal" with Vivid to produce and release a 70-minute film titled, Farrah Superstar: Backdoor Teen Mom.

According to Vivid Entertainment, Farrah Superstar: Backdoor Teen Mom will be available to download through Vivid's website on May 6, and available through retailers on May 14.
