Congratulations are in order for Green Day drummer Tre Cool! On Saturday, Oct. 11, the rock star married Sara Rose, who he has been engaged to since January 2014.

Cool was looking quite dapper in a recent photo he shared on his Instagram account. In the photo's caption, he says, "I'm very happy to have married my best friend Sara ... thanks for all the well wishes an support."

It's been a pretty exciting few days for Cool just before his wedding, he found out that he and bandmates Mike Dirnt and Billie Joe Armstrong were nominated for the Rock and Roll Hall of Fame's Class of 2015.
