Former Miss USA-turned-actress and Tv personality Ali Landry is a new mum - the 39 year old gave birth to her third child, a baby boy, on Thursday (11Jul13).

Landry tipped her Twitter.com followers off about her impending delivery hours before the birth, revealing she had gone into labour.

She wrote, "The time has come. Baby is on his way. On our way to the hospital."

Landry and her filmmaker husband Alejandro Monteverde already have a six-year-old daughter, called Estela, and a 21-month-old toddler, Marcelo.
