Hilary Duff showed off her growing belly Monday before heading into a Pilates class in Toluca Lake, CA.
It may be small, but the bump is definitely there.
The pregnant actress and singer, who is expecting a boy, has been spotted out and about recently, but this is one of the first times her baby bump has really started to show.
But that bump won't be small for long, and Duff knows it. She jokingly tweeted a photo of her posing behind a giant pumpkin, writing, "Oh no I think this is my near future! Baby's getting big! Lol."
And the pregnant star isn't just hitting the gym these days -- she's also hitting the studio! Duff recently announced that she's taking vocal lessons again, just for fun, but hasn't ruled out recording another album and touring after she has her little bambino.
