Two-time Tony winner Sutton Foster paid a special visit to Stephen Colbert on last night's Late Show where, even amid discussion of her television success on TV Land's Younger, her Broadway chops took center stage. Colbert and his guest paid homage to the revival of Cats, now in its second Broadway life at the Neil Simon Theatre, by donning the full feline getup and dueting nose-to-nose in the shimmering moonlight. Although Sweet Charity is next on Foster's to-do list, after watching this performance, Broadway will be clamoring for her Grizabella.
