The 'Younger' star and her husband Matthew Koma have welcomed their second child together, a sibling for their two-year-old daughter Banks and Hilary's son Luca, nine, who she has with her ex-husband Mike Comrie.

Sharing a picture from the birth, Hilary captioned the black and white photograph: "Mae James Bair - We LOVE you beauty 3-24-21 (sic)"

Whilst Matthew wrote in his own post: "Mae James Bair 3/24/21 (sic)"

Meanwhile, Hilary previously revealed her son is being "so helpful" ahead of the baby's arrival as she praised him for always helping.

The 33-year-old actress said: "It's been so cool to be pregnant and have an almost nine-year-old. [Luca is] super compassionate and understanding of the fact that I'm moving a little slower and don't have as much energy as normal. He's so helpful. He jumps to help me when something spills in the kitchen and also great with helping me with bags from the car.

"He's also explaining things to Banks when she doesn't understand what's going on or she doesn't get her way. I notice when she's acting like a two-year-old, he's extra patient with her and begins to sound like me or Matt when he talks to her in an effort to help out or soothe Banks. Banks will kiss my belly, but she hasn't eased up on her daily expectations of me ... It's her world and we're all just living in it! Luca knows what this looks like now from his experience with Banks. He's super excited about the new addition - and hoping it happens on a weekday because he knows he gets to skip school!"

Before the arrival, Hilary admitted she didn't have a "strong feeling" if it was either a boy or a girl when she welcomed the baby into the world.

She said: "Honestly, I'm just saying boy. I really don't have a strong feeling about it either way, which made me feel guilty for the longest time.

"I was like, 'I should know, it's inside my body. It's my baby, I should know.' I don't know, and now I'm okay with just not knowing. But I think it's a boy."
