Reports earlier this week (begs24Jan11) claimed the My Name Is Earl star had split from Singh and it's now emerged she filed for divorce on 21 January (11).
In the legal documents, Pressly cites irreconcilable differences for the break-up, and claims the union ended on 27 December (10), days before she was arrested on suspicion of driving under the influence (DUI).
She is seeking to deny Singh spousal support.
The couple wed in September, 2009 after just months of dating. They have no children together, although the actress is mother to three-year-old son Dezi, from her relationship with former fiance Eric Cubiche.
It's been a tough few weeks for Pressly - in addition to her arrest earlier this month (Jan11), she is also dealing with America's Internal Revenue Service over allegations she owes a total of $637,149 (£424,766) in unpaid taxes.
