During a joint interview in Lee’s cozy dressing room at the New Amsterdam Theatre, the two are as chummy as old friends can be. Both British-born, Kelly, 29, is even doing something very Poppins-ish: sipping tea. Compliments between them seep out easily.

“You are very solid,” Kelly tells Lee at one point. “You’re the rock, which means I can be the water.”

“I love that!” replies Lee, 39.

“I think that’s why we’re such a good team,” she says.
