Which might be the reason for her super-slender new figure, which she showed off to full effect in a gorgeous leather appliqued halterneck dress on the Late Night with Jimmy Fallon show this weekend.
The star was looking teeny-tiny in the LBD, which she matched with a cute honey-blonde side-swept pixie crop and peach-toned make-up.
