Steven Tyler accidentally crashed a wedding in New York.

The Aerosmith frontman and former 'American Idol' judge walked into the wedding reception of Jeffrey Roseman in Washington D.C. last weekend, but rather than sneaking out again, he was more than happy to wish the happy couple well and pose for photos.

Property broker Jeffrey, who married Shirley Ramos, told the New York Post newspaper: ''He could not have been more gracious and accommodating.

''We were convinced that were it not for his ornery bodyguard, we could have had Steven Tyler party with us all night.''

Steven's compassionate side doesn't end there, as Aerosmith played a benefit concert in Japan after their nuclear crisis in 2011, and he explained how he felt the band needed to do it to pay back to a country which has always embraced his music.

He told the Huffington Post: ''We felt in our hearts that there was something we could do and that we should do at that time. Aerosmith's huge in Japan and we have been since the first day we got there.

''I think we took our fear and packed it away. It was time to get them happy, even for a moment. It was kind of like the USO [United Service Organisations], bringing what we've got over to them.

''This concert was a no-brainer. 'Are we going to get hurt?' Of course we went over there with antibiotics and whatever they say to take, but I don't think the radiation was that bad. It was more about making them happy.''
