Grubbs was stopped by authorities because there was a warrant return on the license plate of the 2004 Mustang she was driving.
During the course of the stop, it was discovered that Grubbs' license was still suspended, so she was also cited for that.
She had three outstanding warrants, deputies said. They included: a $26,000 warrant out of Beverly Hills Court for driving on a suspended license; a $2,500 warrant out of Beverly Hills Court for driving on a suspended license; and a $1,809 warrant out of West Los Angeles Court for driving on a suspended license.
Grubbs was taken into custody and released from jail Thursday morning.
The arrest comes a month after Grubbs lost Howard Stern's "Tiger Woods Mistress Beauty Pageant." Girl just can't buy a break.
You'll remember Grubbs as the one who claimed she had a 31-month relationship with Woods and brought these voice mails into the cultural zeitgeist.
