The baby was born a few days ago and still there is no report yet on what name has been chosen for the little bundle of joy, reported E!Online.
The couple's new arrival is not the only secret Worthington, 38, and 27-year-old Bingle have been keeping lately.
For weeks fans have been speculating on whether or not the couple have tied the knot after Bingle was featured on the cover of Gritty Pretty magazine earlier this month with her name written as, Lara Bingle Worthington.
They were first reported to be dating in October 2013.
