Congratulations to Rachel Bilson and Hayden Christensen.
A representative for the couple has confirmed to People that they became a family of three last week - and they also revealed the very unusual name they'd christened their baby daughter with.
They said: "Both mother and baby are healthy and doing well."
It was also revealed that the acting couple had chosen a fairytale-inspired name for their first born.
They've decided to call their child Briar Rose, the name given to Sleeping Beauty in the Grimm Brothers story - and the alias for Princess Aurora in the classic 1959 Disney film.
How adorable!
They're not the first celebs to opt for a fairytale name in recent weeks; Ryan Gosling and Eva Mendes christened their little girl Esmerelda, which - as we're sure Disney fans will know - was the name of the beautiful and kind-hearted gypsy in The Hunchback of Notre Dame.

Maybe the next big baby name trend will be Disney film characters - we bet there'll be an Elsa soon enough in the Hollywood baby bunch.
