Music manager Scooter Braun has shared he's set to be a dad for a third time. Scooter, who represents Justin Bieber and Ariana Grande, announced the happy news on his Instagram account on Monday evening, his 37th birthday.

Sharing a family photo with his wife of four years, Canadian health activist, Yael, 31, and their two sons, the excited music man posted that he got his 'birthday wish'.

Scooter and Yael are already parents to Jagger, three and Levi, one, who pose in the cute Instagram snap with their parents.

Yael is dressed in a colourful bikini for the happy photo as a beaming Scooter tenderly touches her stomach.

Another snap posted by the manager shows his gorgeous wife posing in her bikini in their back garden, cradling her bump.

Alongside the photos, the excited father wrote: 'But the best part of this birthday is I got my wish... OUR wish... #anotherone ❤ @yael.'

Yael also shared the bikini snap as well as another photo taken inside as their two sons peer at their mother's bump.

'Happy Birthday my love, let’s have another baby to celebrate,' she wrote alongside.
