Actress Rosario Dawson and her mum are celebrating Christmas with a cross-country road trip.

The Crash star will celebrate Christmas Day on the move from Los Angeles to the other side of the U.S. in North Carolina in honour of her late grandmother.

She explains, "She passed a few years ago and I miss her a lot. We gave all her Christmas stuff to my godchildren in North Carolina. This is the year we're going to road trip so we could get all that stuff and bring it home."

Dawson gushes over the trove of Christmas items that her grandmother collected, and adds, "There's the old-school plastic tree that I've been putting together since I was a little kid. It's so sparse now... She had every little knick-knack. You could fill up the whole house with everything. She had really beautiful old ornaments, too."
