The Saturdays’ Rochelle Humes announces pregnancy in a very sweet way

It's a week for cute celebrity pregnancy announcements.

Singer Pink took to Instagram at the weekend to announce she was expecting her second child with husband Carey Hart and now Rochelle and Marvin Humes have shared their baby news. The couple posted photos on their respective social media accounts, showing Rochelle tenderly cradling her bump although it's not yet know how far along the singer and presenter is.

Ten tiny fingers, ten tiny toes, but who are you? Nobody knows...??
