ADAM LAMBERT was arrested following a fight with his boyfriend outside a Helsinki, Finland bar on Thursday.
Lambert, 29, and boyfriend Sauli Koskinen, 26, got into the altercation outside a gay bar called Don't Tell Momma, according to Finnish reports.
When patrons outside the establishment tried to stop the altercation, Lambert attacked them as well, though no one was injured.
Koskinen, also a TV star star, won Finland’s 2007 edition of the reality competition Big Brother.
Lambert, who finished second in 2009's American Idol competition to Kris Allen, was still in custody at a facility in Pasila, while Sauli was held at a jail in Toolo, RadarOnline.com reported.
UPDATE: The two lovers were questioned and then released by Finnish cops.
All's Finnish that end's well.
