(Cover) - EN Showbiz - Ryan Reynolds has sparked romance rumours after he was spotted canoodling with a mystery woman.

The Hollywood star has been single since his three-year-marriage to Scarlett Johansson ended last year. The pair are in the process of divorcing, but are still on good terms.

Ryan is currently in South Africa shooting his new movie Safe House, and has been spotted getting close to a gorgeous woman. The unknown female has short blonde hair and has accompanied the hunk to the film set, where she was spotted with her hand on his butt. They later left together with their arms around each other.

We got these supercomfy photos of Ry getting touchy with a young, pixie-cut-rocking hottie. Her hand is pretty close to Ryan's nice backside isn't it? reports E! Online.

It was first thought the woman might be one of the cast members, but that has since been ruled out.

Ryans representative has not commented on the reports.

Scarlett has been linked to a number of men since the union broke down, most recently Jude Law and Sean Penn. Her representative has denied she is dating Sean, although the 26-year-old was recently spotted lunching with him with her foot in his lap. (C) Cover Media
