Alessandra Ambrosio looked ready to pop as she posed on the beach just a few days ago, and she's done just that after giving birth to a baby boy.

Her fiancé's mum, Michelle Mazur, confirmed the news on her Facebook page, writing: ''Grandson just born in Brazil!'''

And it wasn't long until her fiancé - and very proud dad - US businessman Jamie Mazur, also shared the news with the world, tweeting: "Welcome my son, can't wait to show you around this crazy place."

This is the couple's second child - they are also parents to daughter Anja, 3.

The arrival of their latest addition comes just a few days after her baby shower. On Saturday the Victoria's Secret model tweeted: "So much fun at my little boy baby shower! Now just have to wait for him to arrive!"

She didn't have to wait long! Congrats to them both.
