Rocker Adam Lambert has reportedly been released from custody following his arrest in Finland for an alleged brawl with his boyfriend.

The former American Idol star was taken in by cops in the early hours of Thursday morning after becoming embroiled in a feud with his Finnish-born partner Sauli Koskinen at Helsinki gay club Don't Tell Mama.

The pair was reportedly sent off to separate prisons, but they have now been questioned and released as neither suffered any injuries, reports TMZ.com.

Koskinen has already taken to his online blog to comment on the incident in his native tongue, reportedly writing, "Publicity is not easy, but also celebrities are just human. Love is not easy either, but it lasts forever!"
