“When I go into 'You're the Worst,' I'm very glammed up, and my hair and makeup is va-va-voom. Now what I'm having fun with in 'Grease' is, honestly, I go to rehearsals with zero makeup. When I get pimples, I get excited about it, like 'Yay! It helps the character!' The frumpier and uglier and grosser, the better with Jan.”
