Bai Ling can't seem to catch a break these days!  Whether it's another direct-to-DVD feature or a stint in "Celebrity" Rehab, this Chengdu-born starlet has had her fair share of oops moments.  But holiday oops?  Now that's a new one!  Ling was spotted shopping for a last-minute Christmas tree in Hollywood when paparazzi caught the actress using a handicap port-a-potty—in heels, no less.  Check out some pics of Bai's haystack/giant bow "photoshoot" below.

When will Bai learn?
