Allison Janney from Mom
We already know this Mom star is an award-winning actress, but did you know she can also hit some impressive high notes? Though Allison Janney never really considered herself a singer, fans would say otherwise after hearing her belt out "One Of The Boys" and "On The View" as Violet Newstead in the Broadway musical 9 To 5. She even took home a Drama Desk Award for Outstanding Actress in a Musical and a Tony nom for her performance. Props.
Watch Mom on CBS.
