Former American Idol runner-up Adam Lambert was reportedly arrested and thrown in the slammer in Finland early Thursday morning (Wednesday night) after he got into a fight with his Finnish boyfriend Sauli Koskinen, who is a local reality star.

Petri Juvonen, who is over the investigation, told The Hollywood Reporter that Lambert and his boyfriend were arrested at around 4am this morning after they got into a heated argument outside a famous gay club called “Don’t Tell Mama” in Helsinki, Finland. Both men were held for questioning, and were released after a few hours.

Media reports from Finland say the fight between the two lovers started in one of the club’s back rooms, before it eventually spilled into the club’s main area.

After bouncers kicked the men out of the club, they continued to fight outside in the street, where witnesses say Lambert got physical with the people who tried to break up the fight.

Finnish beauty queen Sofia Ruusil, who had been partying with Lambert and his boyfriend, was reportedly at the bar and tried to get in between the quarreling couple when the fight escalated. She claims that Lambert accidentally hit her in the process.

Lambert had arrived to Finland on Monday (Dec 19) to celebrate Christmas with Koskinen, who Lambert has been dating since 2010.

MTV News points out that the couple are a true match:

Adam Lambert and Sauli Koskinen are a true reality couple. Lambert rose to fame as a genre-shaking “American Idol” contestant, finishing second, but turning the relatively safe song choices and performances on their ear during an electrifying 2009 season.

Following the conclusion of the season, Lambert came out during an interview with Rolling Stone.

Koskinen made his claim to fame by winning the Finnish version of “Big Brother” in 2007. The two began dating in 2010.

After Lambert and Koskinen were released from custody, Koskinen later blogged about the incident (as translated by Google via THR):

“Celebrities are people too and fame is not easy. Love is not always easy either, but it’s forever.” Koskinen goes on to say that the “hangover is gone already” and “Paparazzi, police stations have back doors, too, go away already.”

Shortly after Koskinen published his blog post, Lambert followed suit, tweeting:

“Jetlag+Vodka=blackout. Us÷blackout=irrational confusion. jail+guilt+press=lesson learned. Sauli+Adam+hangover burgers= laughing bout it. :)”
