Poppy Montgomery will surely consider Nov. 11 as another unforgettable date in her life. For one thing, it's the date of birth of her third little bundle of joy.

Just this Tuesday, the "Unforgettable" actress and her husband, Shawn Sanford, welcomed their third child, a healthy baby boy, the Hollywood celeb's rep confirmed to Us Weekly.

The third child of the Australian-American actress named Gus Monroe Deveraux Sanford reportedly weighed 7 lbs., 4 oz., and measured 20.5 inches long.

"We couldn't be more excited to welcome baby Gus into our family. We will be forever grateful for his healthy and happy arrival," Sanford said. "His brothers and sisters cannot wait for him to be home even though we keep reminding them that baby Gus is not a toy."

Gus is considered the third child of the couple since he is joining his older siblings: 19-month-old Violet Grace and 6-year-old stepbrother Jackson, who is Poppy Montgomery's first child from a previous relationship.

In an interview on "Late Show with David Letterman" in July, the 42-year-old "Without A Trace" star revealed that she and her Microsoft executive were already expecting, confirming pregnancy rumors that surfaced that time.

"I'm expecting!" she told Letterman. "I'm far down the road of expecting...I'm six months pregnant. I've been hiding it until this very moment."

She then joked about getting privileges because of her pregnancy saying, "I'm hoping to get all of the privileges now of a real pregnant person. I want to be respected and given lots of royal treatment."

"A name. THE name. The name that my unborn son will carry with him for the rest of his life. What if I mess it up?" she added at the time, according to People.

While this is technically Montgomery's second child with Sanford, Gus is actually Shawn's fourth child since he already has two kids from a previous marriage: daughter Haley and son Braydon.

Poppy Montgomery and Shawn Sanford tied the knot in February at Disneyland. She was previously in a serious relationship with actor Adam Kaufman - the father of Jackson - but they split in October 2011, Daily Mail has learned.
