"I'm very lucky that 31 years into our friendship, he's still my best friend in the world. He's a really great guy. I see him a lot; I speak to him a lot. You know, he's now a father of five; he has five kids and he's a great dad. Yeah, he will remain my best friend for life," she said.
Grant's representatives have not commented on the news yet. The gender of the child is unknown.
Hurley, who dated the "Paddington 2" actor for 13 years, also dished more details about his newborn when she appeared on Bravo's "Watch What Happens Live With Andy Cohen".
"He had another one last week. He has five. He was over 50 when he spawned them all! He's an enchanting dad - really, really sweet. Having these kids has transformed him from a very miserable person into a fairly miserable person. It's improved him. He's gone up the scale," she had said.
This is Eberstein's third child with Grant.
The actor has two children with Tinglan Hong.
