and his boyfriend, Finnish reality star Sauli Koskinen, were both jailed in Helsinki early Thursday morning after reportedly getting into a dispute that led to a physical altercation at a bar.
Lambert, 29, a former American Idol runner-up
, and Koskinen, 26, a winner of the Finnish version of Big Brother
, were held for questioning as local police looked into four possible assault offenses, according to the Hollywood Reporter.
They were released Thursday afternoon. Koskinen then blogged about the incident, suggesting the pair had patched things up.
"Fame is not easy. Celebrities are only human. Love is not easy either, but it is forever!" he wrote, adding that it was a private matter.
The two were reportedly kicked out of a bar called Don't Tell Mama, but continued fighting on the street outside. Finnish beauty queen Sofia Ruusila, who was partying with them, was allegedly struck accidentally during the fracas.
Later on Thursday, Lambert Tweeted about the incident in a playful message which seemed to indicate alcohol played a part – and that he had learned his lesson.
"Jetlag+Vodka=blackout," he wrote
. "Jail+guilt+press=lesson learned. Sauli+Adam+hangover burgers= laughing bout it."
It is unclear whether either man would face any charges connected to the fight.
Lambert's reps were not immediately available for comment.
