Poppy Montgomery's pregnancy has come up roses — and it’s a girl!

The Unforgettable star and her boyfriend, Microsoft executive Shawn Sanford, welcomed their first child together on Monday, April 22, her rep confirms to PEOPLE exclusively.

Daughter Violet Grace Devereux Sanford arrived at 7:57 a.m., weighing in at 6 pounds, 12 ounces and measuring 19.5 inches long. She joins big brother Jackson, 5, Montgomery’s son from a previous relationship.

“We are overjoyed with the arrival of our beautiful angel and filled with gratitude that she is happy, healthy and thriving,” the couple tell PEOPLE.

After announcing she was expecting a baby girl with Sanford, whom she began dating in late 2011, the PEOPLE blogger realized curbing her cravings wasn’t so easy.

Also known for her role on another CBS detective series, Without a Trace, Montgomery will be back on the small screen when the canceled-then-resurrected Unforgettable returns for its second season on Sunday, July 28 at 9/8c on CBS.
