The singer made the announcement on her official website with the short but sweet message:
"It's true I'm going to be a mummy!"
She had been keeping mum on her growing tum over the last couple of weeks, with rumours circulating she was trying to secure a whopper of a media deal to reveal her and fiancé, Eric Johnson's news.
Congratulations Jessica and Eric - although officially the worst kept secret since Mariah's twins!
