In case you haven't heard, Sienna Miller's sister Savannah confirmed that the actress is preggers with her supposed fiancé Tom Sturridge's baby.
But, now we've learned WHEN Sienna is due to give birth!
She's due to give birth in July.
That means she's only about 3 months preggers now so she still has time to ease into pregnancy.
We bet she's just over the moon with the news! Congrats again!
