The former 'Without a Trace' star and her husband Shawn Sanford will welcome a new sibling for their 14-month-old daughter Violet Grace this autumn, reported Ace Showbiz.
Montgomery, who is already six months pregnant, confirmed the happy news during an appearance on US talk show 'The View'.
Excited to finally talk about her pregnancy in public, she said, "I'm so happy. 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."
"I haven't told anyone yet."
The 39-year-old actress also has a six-year-old son, Jackson, from her previous relationship with actor Adam Kaufman, while Sanford has two other children from a prior marriage.
