Next role for Jeremy Renner: Dad

Jeremy Renner is going to be a papa.

An ex-girlfriend of the "Hansel and Gretel Witch Hunters" star is pregnant with his child, according to Us Weekly.

"They used to date but it wasn't serious," a source told the magazine, adding that the woman - whose name is unknown - is currently living at Renner's home in Los Angeles.

According to the mag, the normally private 42-year-old actor was overheard sharing the news with actress Eva Longoria during the Golden Globe Awards on Sunday night. Her response? "I'm so blown away," the mag reported.
