Ashlee Simpson was spotted heading into Mr. Chow in London sporting some eye-popping cleavage.

Dressed to kill with knee-high black leather boots and flashing her lacy bra for all to see, the younger Simpson was definitely looking for some attention as she met up with Jessica at the restaurant.

The Simpson sisters are in London for Ashlee's debut as Roxie Hart in a stage production of the musical "Chicago," where she's garnering surprisingly positive reviews.
