Katy Perry expecting first child with Orlando Bloom

The 35 year old, who got engaged to 43 year old Orlando last year, announced the news during an Instagram Live video, where she told her 90.5 million followers: "I've always known I'm a mother, a mother to the kids."

At the end of the clip, which is thought to be a love ballad to her fiancé, the singer, Katy can be seen wearing a gorgeous white gown with a plunging neckline and turns to the side to reveal her gorgeous growing bump.
