My Chemical Romance bassist Mikey Way has taken indefinite leave from the band to spend more time with his new wife.

Mikey - younger brother of frontman Gerard - tied the knot with Alicia Simmons at a gig in Las Vegas last month and is now taking a "much needed break" to enjoy married life.

"Watching [Mikey] grow up into a man and finding love makes me the happiest brother alive," said Gerard in a statement on the band's official website. "In light of this joyous event, the band has decided to give he and his wife a much needed break from the road to start a life and have a proper honeymoon and do all of the things a newlywed couple should do.

"I know this is upsetting news, as it is for us, but we will continue to tour with a temporary replacement until he has situated himself in his new life."
