Lenny Kravitz -- I'm Committed to Leather ... Penis Escape was a One-Off

Lenny Kravitz will NOT 86 leather pants from his tour, despite the biggest wardrobe malfunction in history.

Our sources say, Lenny was privately horrified his penis made a grand entrance during a concert after his tight leather pants exploded.

A lesser man might hang up the leather for a safer pair of trousers, but the 51-year-old is not deterred. We're told he will continue to wear leather.

Some thought he'd hold a grudge against Saint Laurent, the manufacturer. But Lenny is chalking it up to a bad pair, and will continue to wear the duds during his show.

Lenny continued his European tour Thursday in Denmark. Come to think of it, if it happens in Denmark it's probably no big deal.
