Will Ferrell was on The Late Show with David Letterman yesterday promoting his movie Megamind, but he also previewed something else he is working on right now. Celine Dion just became a mom again to twins Eddy and Nelson and she is on maternity leave from her Vegas show. Well her good friend (who knew) Will is filling in for her and yesterday on the CBS talk show he sang one of her biggest songs Power of Love. Let’s just say after that twins retreated back into their mother’s womb where it is nice, quiet and safe. Part of me after that wishes I could join them.
