Conan OBrien, too, is known for his upbeat demeanor.

When Im not smiling, people think Im furious, Kemper said.

People are used to seeing me like, Hey, everybody!

This is me driving on the 405 home at night.

I have clear windows.

People are probably like, I saw him!

Theres something wrong with him.'

Kemper is especially worried because she thinks all her smiles are giving her wrinkles.

As Kemper has learned from her dad, refraining from showing emotion has its benefits.

He does not make a lot of expressions.

He is in his 60s, not a line on his face, Kemper said.

I think it pays off, from a lifetime of not expressing anything.

Thats the Rob Lowe secret, OBrien quipped.

Never enjoyed a moment of his life.
