"Jon & Kate Plus 8" stars Kate and Jon Gosselin's marriage is over. Documents for a legal separation were filed at the Bucks County Courthouse in Reading, Pa., this afternoon, according to People magazine.

Fans of the TLC show are likely not surprised. The reality stars had long maintained a tense relationship, with Jon recently telling People magazine he wanted a less high-profile life, while Kate appeared to remain committed to their TV career.

The couple was expected to announce the news on tonight's all-new episode of the show at 9 p.m. ET.

UPDATE: Watch the official divorce announcement video...PLUS show will go on hiatus!
