So You Think You Can Dance Season 4 winner Joshua Allen has been charged with three felony counts and four misdemeanors after allegedly attacking his girlfriend.

Allen, 27, is facing two felony counts of willfully injuring his girlfriend, one felony count of assault with a deadly weapon, and four misdemeanors related to battery, vandalism and violating, TMZ reported.

Prosecutors plan to ask for $270,000 bail, and if Allen is convicted, he could face more than 10 years in prison.

Allen reportedly beat up his girlfriend twice in a two-month span.

According to the D.A.'s Office, Allen chased his girlfriend into a coffee shop last month, and when a witness attempted to intervene, Allen allegedly threw a glass vase at her and vandalized the shop before bystanders stopped him.

Allen originally auditioned in 2008 for So You Think You Can Dance in Dallas, TX with his friend and fellow contestant, Comfort Fedoke, who currently serves as an All-Star on the series' Next Generation edition.
