As NBC’s “Undateable” begins its second season Tuesday, showrunner Bill Lawrence is looking to shake things up with the comedy's format.

It was revealed that NBC has given Lawrence and the gang the OK to air a one-hour live episode on May 5. As with the two episodes NBC gave “30 Rock” during its fifth and sixth seasons, the "Undateable" cast will perform the episode live twice, for the East Coast and West Coast broadcasts, according to a press release from the network. In a recent interview with the media, Lawrence -- the creator of  “Scrubs,” “Spin City” and “Cougar Town” -- said a live show isn’t the only change coming.

“The biggest change on the show is -- for me, it was we added a new cast member," he said, referring to Bridgit Mendler, most recently the star of Disney Channel's “Good Luck Charlie.”

In addition to now playing a bartender named Candace in "Undateable," Mendler is a successful recording artist with a built-in fan base. Lawrence says her background has made her a powerful asset to the show already. He shared a story with the press in which Candace was writing a song for a boy she likes. She’s supposed to sing it to the “Undateable” gang and, when the cast showed up on the set that day, the actress had written a “beautiful minute-long song.” With so much musical creativity being brought to the set, Lawrence decided to lean into the storm.

“If you watch my TV shows, I’m a sucker for music, you know?" he said. " 'Scrubs' -- we had an a cappella band. We had Colin Hay. We had, you know, Joshua Radin singing 'Alive.' We had tons of indie music, and the same with 'Cougar Town' -- even back in 'Spin City.' ” He added: “Bridgit is a recording artist. Not only will the cast be singing, but much as it is in real life, whenever they do, it drives Chris D’Elia insane.”

“Undateable” focuses on mismatched roommates Danny Burton (D’Elia) and Justin Kearney (Brent Morin) and their strange friends Shelly (Ron Funches), Burski (Rick Glassman), Brett (David Fynn) and Danny’s sister, Leslie (Bianca Kajlich) – each of whom is in some way undateable.

Season 2 of "Undateable" will premiere Tuesday at 9 p.m. EDT following “The Voice.”
