Hilary Duff proved her divorce proceedings are amicable by heading off on a family hike with her estranged husband over the weekend (25-26Jan14).

The star announced her split from Mike Comrie earlier this month (Jan14), and subsequent reports suggested the marriage had been in trouble for some time.

Duff, who shares a 21-month-old son, Luca, with Comrie has now proved the former couple is still on good terms by arranging a family day out.

The star went hiking with Comrie and Luca in California on Sunday (26Jan14) and posted pictures from the outing on her Twitter.com page, writing, "Daddy & son Sunday hike."

The former couple wed in 2010.
