Model and singer Suki Waterhouse has confirmed the birth of her first child with Twilight star Robert Pattinson.

The British star, 32, shared a Polaroid of her cradling her child, who was wrapped up in a blanket adorned with love hearts.

"Welcome to the world angel," she wrote on Instagram, adding a red, love heart emoji.

Waterhouse first appeared to confirm her pregnancy on stage at a festival in Mexico last November.

She told concertgoers she had specifically chosen to wear something sparkly to "distract" from "something else" - insinuating her growing baby bump.

She later posted a series of photographs from her performance, including a picture where her baby bump was visible.

Waterhouse is believed to have been dating Pattinson, 37, on and off since 2018.

The actor, who found fame starring as Edward Cullen in the Twilight saga films, has followed in the footsteps of Christian Bale, George Clooney and Ben Affleck playing Batman in the superhero franchise.
