Showing off the singing training from her recently released musical, the 30-year-old actress sang with her mother Kathleen, reported Contactmusic.
Hathaway, whose husband Adam Shulman is Jewish, said, "Christmas is good, we usually go and spend it at my dad's family's house and my mum's family's house. My mum's family's house is really fun because we do a lot of carolling."
"We stay in the house and my godmother plays the piano I think once a year, and I think it's Christmas. So we sit around... And we all sing for like an hour or so. It's really, really fun," she added.
