Rachael Leigh Cook and Daniel Gillies are now parents to a baby girl.
The "She's All That" alum and "The Vampire Diaries" actor welcomed their first child together, according to Gillies.
"it's a girl," the actor tweeted Sunday with a little poem. "the tiny new empress of my everything. she's immaculate. we're delirious."
This is the first child for the new parents, who married on Aug. 14, 2004. The couple did not release any further details regarding their daughter's name, birthdate or vitals.
News broke Friday that the couple had had their baby, but details were sparse, and Gillies took to Twitter then to set the record straight.
"beautiful people: baby has not arrived. yet," he wrote. "please disregard the gossip+misinformation. we'll keep you posted. Xx love d+r+?"
As of last May, when Cook and Gillies announced they were expecting, Gillies, 37, seemed pretty keen on the odd celebrity baby name trend.
"A lot of people are asking whether I'd prefer a boy or a girl. In truth, it doesn't matter to me — I just can't wait to meet little Keanu Robocop," he joked.
It's going to be a busy year for the couple. Cook is starring in TNT's "Perception" with "Will & Grace" alum Eric McCormack.
The British actor will also reprise his role as fearsome original vampire Elijah Mikaelson in "The Vampire Diaries" spinoff, "The Originals," on the CW. The series premieres Thursday.
