The couple posted the adorable snap on John's Twitter page earlier today (May 13).
In the picture, 3-month-old Hazel can be seen gazing into the camera, wearing, what looks like a pink Ralph Lauren onesie.
Alongside the photo, proud dad John wrote: "Pics of kids should only come direct from parents. So I'm thrilled to introduce you guys to Hazel!!!"
British actress Emily, 31, gave birth to Hazel in February. She got together with American actor John, 34, in 2008, after splitting from singer Michael Bublé.
They married in Lake Como, Italy, in 2010.
Last week it was reported that the couple are moving house, after snapping up a £4m mansion in the Hollywood Hills.
