Eminem's ex-wife Kim Mathers was in court on Monday after failing her alcohol and drug tests, and as such, her probation.

Mathers was on probation after being convicted of drunk driving, and failed her tests on multiple occasions between December and Feb. 1, according to local Detroit press.

Mathers' lawyer argued on Monday that she had failed these tests because she was not properly advised about the intricacies of how she would violate them. The tests are reportedly sensitive, with the attorney noting that they can be triggered just by consuming coffee or a lot of water.

She has been using Soberlink, a portable breathalyzer that more accurately assesses alcohol consumption. Monday's judge said he was "impressed" by Mathers ordered that she should continue using Soberlink, with more tests, for 90 days.

Mathers had previously pleaded no contest to drinking and driving in October, and was sentenced to one year of probation the following month.

The Detroit native is the ex-wife of Eminem, a.k.a. Marshall Mathers. The rapper has referenced Kim numerous times in songs, including the controversial "Kim" from The Marshall Mathers LP. The song features Eminem rapping about his volatile relationship with Kim, including an elaborate fantasy sequence in which he envisions Kim killing her new husband, her child and then herself.

The hook, however, shows their true passion for each other even while knowing they drive each other crazy: "So long, b----, you did me so wrong / I don't wanna go on / Living in this world without you."

Eminem's song "97' Bonnie & Clyde" from The Slim Shady EP isn't much better, where the rapper drives with his daughter Hailie to go dispose of Kim's body.

After divorcing in 2006, Eminem and Kim agreed to joint custody of Hailie.
