Ashlee showed off her bubble gum-esque LPD and bright white smile at an event for Stride Gum at Teddy's in Hollywood last night. The Duff girls and, somewhat random but always nice to see, Winona were also in the house for the party (and some free gum, natch). Unfortunately Ash's big sister Jess was nowhere to be found -- but considering the amount of time she's been spending at the gym recently, it's clear she doesn't have time for much else. Also not around to celebrate was Ashlee's BF Pete Wentz. It's a shame, too, because his girl was looking pretty darn adorable!
