Richie - Out of Rehab!

From TMZ:

Sambora told our photog at JFK he was feeling good -- which was evidenced by the fact he signed dozens upon dozens of autographs for fans.

He arrived from Los Angeles, but planned on heading right back out -- he's meeting up with Jon and the boys for the European leg of the tour. They are scheduled to play in Croatia on Wednesday.

Sambora checked himself into rehab in late April after, we're told, he fell of the wagon.

For some reason I couldn't embed the video, but you can see it here.
