Jennifer Hudson never seems to stop working!  The singer/actress/mommy hit the set of NBC's "Smash" yesterday to film her guest spot on the upcoming second season.

Get the flicks inside...

Jenny is busy filming a multi-episode arc on NBC's hit musical drama "Smash."  And yesterday, she was spotted on the New York set with co-star Jack Davenport in a vintage glamour girl look of a fitted green & black printed dress, black pumps, and a vintage hairstyle.

She will play "Veronica Moore," a Tony Award-winning Broadway star who'll have scenes with both star Katherine McPhee (her fellow "Idol" alum) and Megan Hilty.  Her character will be one who has great roadway talent, and even achieved her dream, but will pay a price for it.

She made a few few wardrobe changes as well:

And look who else was on set:

Little David, Jr. (in his little crocs) and his nanny. Awww.  The new season of "Smash" kicks off later this year.

1. WHO KNEW that Rita Ora & Bruno Mars used to be so in love and a serious couple?  Up until their break up last year because of "fame."  STORY
