Julia Roberts will celebrate Earth Day today by showing off her compost skills on TV. The Oscar winner recently joined pal Oprah Winfrey to tape a segment for a green-themed show, during which she shows how to mulch your own compost heap.

The glamorous mom-of-three quipped, "I'm usually dressed like this when I do it."

Sandra Bullock, who was involved in a car crash in Massachusetts on Friday night, also taped a segment for the show before she hit the headlines over the weekend.
