But who's going to stay with Demi Moore over the holiday?

Rumer and Tallulah Willis won't be with their mom this Thanksgiving -- we spotted the girls with dad Bruce Willis and stepmom Emma Heming at the Roissy Airport in Paris this morning, and Rumer tweeted, "Off to Paris I go!! Can't wait to see my beautiful lil sis at the Crillion ball." Hmm, maybe Scout stayed behind with Demi?
