Del Toro and Keener dating, say reports

Hollywood stars Benicio Del Toro and Catherine Keener are secretly dating, according to reports.

The pair was spotted enjoying a meal together at Los Angeles restaurant Green Door last week - and onlookers claimed love was in the air.

A fellow diner told OK! Magazine: "He whispered into her ear, and she listened with rapt attention. He brushed his hand on her back. They had nice chemistry."

'Being John Malkovich' star Keener divorced husband of 17 years Dermot Mulroney in 2007. Del Toro is single and has never married.
