Chris Carmack of Grey's Anatomy fame and his wife Erin Slaver have welcomed a second daughter.

The two, 41 and 34, recently took to Instagram to announce the happy news in a joint post with photos of their baby girl.

'We had a baby!' it began, continuing, 'Cielle Estee Carmack, (means the sky and the stars) and that’s exactly what she is to us!'

The couple noted that their little one arrived early as they added, 'Born 2 weeks early on May 10th, she was the best surprise we could’ve imagined!'

Cielle joins big sister Kai, who will turn six in August. The happy parents shared that they were expecting a second child back in March.

At the time they wrote in an Instagram post, 'How do you celebrate your second baby girl?? With a FIESTA course!'

They excitedly noted, 'We are about nine weeks away! Thanks to all the wonderful friends who came to celebrate and to everyone who made this party unforgettable!'

Chris and Erin have been married since 2018 and also share a music career together, performing as Life on Eris.

The spouses first met on the set of Nashville when Chris portrayed country crooner Will Lexington and Erin served back-up singing duties for Hayden Panettiere's character Juliette Barnes. 

Since tying the knot several years ago in October 2018 they've documented their lives together on social media.

The duo appear to be head over heels in their lives as parents.

Back in August Carmack took to Instagram to share a precious outtake as they celebrated Kai's fifth birthday.

'When your daughter turns 5… it’s a black tie event,' he wrote under a photo of the trio enjoying a backyard picnic.

The actor was dressed in a tuxedo, his wife wore a white dress, and Kai donned a pink frock with a tulle skirt.
