Nikki Reed has filed for divorce from Paul McDonald.

The Twilight Saga actress, who announced her separation from the former American Idol contestant in March and is rumored to be dating Dancing With the Stars star Derek Hough, filed courts documents to legally dissolve their marriage in Los Angeles Superior Court on Friday.

The 25-year-old star cites irreconcilable differences and asks that her estranged husband, 29, be denied spousal support, according to court documents obtained by PEOPLE magazine.

The former couple, who tied the knot in October 2011 after a whirlwind romance and quietly ended their relationship eight months ago, previously insisted their split was amicable. Announcing their separation two months ago, a spokesperson for the actress said they were "still working [together] on their debut album, I'm Not Falling, and added, "[They] remain best friends and look forward to their continued journey together."
