(Cover) - EN Showbiz - Jim Carrey and his mystery girlfriend wore matching leather outfits to a Guns N' Roses concert last night.

The pair were photographer getting ready to rock out at the reunion concert at The Forum in Los Angeles.

Jim wore a black leather jacket, black jeans and a t-shirt declaring his love for rock n' roll.

His mystery companion wore her blonde curly hair loose, skin tight leather pants and towering Christian Louboutin black-studded heels.

The couple were holding hands and smiling as they walked past photographers.

The duo were first spotted out together last month in New York, but the identity of the star's new lady love is still a mystery.

Jim has been largely single since splitting from his girlfriend of five years Jenny McCarthy in April 2010.

In the past the actor has been married twice. The first time was to waitress Melissa Womer in 1987 which ended in 1995. The pair have a 23-year-old daughter called Jane.

The star also wed his Dumb & Dumber co-star Lauren Holly, but the union lasted less than a year.

Earlier this year Jim declared his love for actress Emma Stone with a comedy video on his blog.

"Emma, I think you're all the way beautiful. Not just pretty, but smart and kind-hearted. And if I were a lot younger, I would marry you," he said in the clip. (C) Cover Media
