London, Aug 10 - Pop diva Madonna's ex-husband Guy Ritchie is dating 'Iron Man' actress Mellany Gandara.

The filmmaker split from Madonna in late 2008 after almost eight years of marriage. Now he is moving on by stepping out with 26-year-old Gandara, who he met through mutual friend Robert Downey Jr, reported femalefirst.co.uk.

The two have been spotted on a series of dates, including an outing to Ritchie's London pub, The Punch Bowl.
