The "I'm a Survivor" singer has teamed up with renowned songwriter Carole King to write the theme song to her new NBC comedy, “Happy’s Place.” On the Oct. 11 episode of TODAY, viewers got an exclusive preview of the song when it was aired exclusively on PopStart.

In an exclusive conversation with PEOPLE at NBC's Comedies celebration with PEOPLE and Entertainment Weekly, Rex Linn shared how he and his girlfriend Reba McEntire snuck by for a "quick kiss" while filming 'Happy's Place'.
