It appears that when "American Idol" star Adam Lambert and his boyfriend Sauli Koskinen get into a fight, things get quite heated. How else to explain that Lambert spent several hours locked up in a Finnish jail cell following a clash with Koskinen?

TMZ reports that an argument between the two started inside of a bar in Helsinki and ended up on the street. Lambert allegedly was physical with the locals who tried to separate the two. When police arrived on the scene, both men were taken into custody. Talk about a public display of aggression.

Petri Juvonen, who is heading the investigation, told The Hollywood Reporter that the arrests were made at 4 a.m. Thursday outside of DTM (Don't Tell Momma), a well-known gay club. Juvonen said that the couple was released after an interrogation. Sofia Ruusila, an ex-Miss Helsinki, reportedly was at the bar and tried to get in between the couple when the fight escalated. She claims that she was accidentally hit by Lambert in the process.

Lambert and 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.

The trip was to be a fun one for Lambert, who tweeted in Finnish his excitement upon arrival on Wednesday that "Helsinki is a beautiful city full of beautiful people! Thank you!"

But Lambert had to follow that up with this tweet to try and explain himself: "Jetlag+Vodka=blackout. Us÷blackout=irrational confusion. jail+guilt+press=lesson learned. Sauli+Adam+hangover burgers= laughing bout it. :)"
