Ben Affleck and Jennifer Garner will be beaming with joy after the actress finally gave birth to a baby girl yesterday.

The Juno star - who has been looking fit to burst for weeks now - was rushed to a Los Angeles hospital on Tuesday where she gave birth to a younger sister for three-year-old daughter Violet.

The actress's rep confirmed, "Jennifer Garner and Ben Affleck gave birth to a healthy baby girl."

The couple announced they were expecting a second child in July after speculation surrounding Jennifer's rounded tummy.

In the weeks leading up to the birth, the actress stayed close to home, picking up Violet from preschool and treating herself to some much needed creature comforts.
