Lady in Red: Gwen Stefani shows off her slim post-baby body in vibrant suit

We think an age investigation needs to be launched. Because we just DO NOT believe that Gwen Stefani is really 44.

LOOK AT HER.

The blonde bombshell looked a vision of youth and beauty when she stepped out in New York City in this scarlet red suit on Thursday morning.

The L.A.M.B creator was all smiles as she showed off her super svelte post-baby body on her way to the Today Show studios.

The glam mum-of-three wore her choppy blonde locks in chic curls and her statement red lippy.

The No Doubt frontwoman  is said to be joining the The Voice USA show while Dirrty singer Christina takes a season off to concentrate on her pregnancy .

TMZ cites multiple sources connected to the singing competition as confirming the 44-year-old singer will join for the seventh season of the show, which will start filming in June.

Christina - who is pregnant with her second child - would reportedly be nearly full-term by the time the US competition reaches the battle rounds stage, making it difficult for her to continue for this season.
