Kate Middleton revealed when Prince George will be a big brother. 

The Duchess and her husband Prince William are expecting their second baby at "mid-to-end of April," she said to a volunteer who asked her at the Brookhill Children's Centre in Woolwich on Wednesday.

Kate, 33, was meeting with parents and visiting an on-site nursery at the children’s centre. The centre is run by Home Start charity, an organization with a network of 15,000 volunteers that help parents and young families.

One question still remains though, the baby's gender. The royals are still keeping mum about that, but many are speculating based on Kate's fabulous maternity wardrobe. Just last week, she wore light pink, which may be a sign for a baby girl, but then again, she did wear that same jacket with Prince George!

Will and Kate first announced that they were expecting on Sept. 8 of last year. Their oldest child Prince George will turn two on July 22, just a few months after their second child's due date.
