Up All Night is hosting a Bluth family reunion!

Arrested Development's Tony Hale is heading to the NBC comedy to reunite with his former TV brother Will Arnett, TVGuide.com has learned exclusively.

Hale will play Dr. Welborn, Reagan's (Christina Applegate) dentist. Dr. Welborn is always super flirty with Reagan and boosts her ego after she's called "ma'am" by a bunch of twentysomething hipsters.
