TVLine describes Lee's character as a "sweet and good-looking" single dad.
'Up All Night' premiered to solid ratings and looks like it may be NBC's latest breakout comedy. The show stars Christina Applegate, who works for Rudolph's character, and Will Arnett as thirty-something first-time parents struggling with the new responsibility.
Lee's role on the TNT cop drama 'Memphis Beat' is still in limbo. The show wrapped its second season but the network has not yet ordered a third.
In a September interview with AOL TV, Rudolph described her character Ava's romantic life:
"My character is definitely one of those working women who put career first, but then I think you'll see that she's got questions of her own. Do I want to settle down? Some people don't want to have kids, they don't want to settle down. Everybody's got their own trajectory. I think that's something that's good to look at, too -- it's not just a million people with children on the show."
