Los Angeles, Jan 27 (IANS): Actress and singer-songwriter Hilary Duff went on a family trip with her estranged husband, retired professional ice hockey player Mike Comrie, and son Luca.

The family of three headed out for a hike Sunday, reports eonline.com.

"Daddy and son Sunday hike," Duff posted along with a photograph of her estranged husband and their 22-month-old tot walking on a trail.

The 26-year-old actress made her first red carpet appearance post-split at the 2014 Grammy Weekend Reception party in West Hollywood, California.

While she stayed mum on the break-up at the event, she seemed to be in great spirits while chatting and laughing with friends before Lorde performed for guests.

A source close to the couple told E! News that the couple's split was truly amicable and they didn't call it quits for any particular incident. The duo rather drifted apart over time despite trying couple's therapy to mend their relationship.
