Katharine McPhee Shares First Photos of Son's Face as Husband David Calls Her a 'Hot Mom'

Katharine McPhee is one "hot mom," according to husband David Foster.

The actress, 37, shared a series of photos from a recent family trip to Canada on Thursday. Included in the post were two snapshots of McPhee holding 6-month-old son Rennie David.

In one of the photos, McPhee is holding Rennie as she waves at the camera from a trail in a sunny garden. Another photo showed the Smash star giving Rennie a big smooch on the cheek in front of a body of water.

"HOT MOM!!!!! 🔥 " Foster, 71, commented on the post.

The pictures appear to be the first time McPhee has shared photos of her little one's face; she has previously included Rennie in photos with his back to the camera or his face obscured.

McPhee and Foster welcomed Rennie in February after tying the knot in June 2019.

The American Idol alum said in April that being a mom is the "greatest job" she will ever have.

"He's such a good little baby and I'm so in love," she told Kelly Clarkson during an appearance on the singer's talk show.

In July, she told PEOPLE that Rennie is "advanced" in his developmental milestones.

"His little teeth popped out and it's fun because they popped up earlier than when they were supposed to. He's a much bigger baby than his peers, so it's kind of fun to have a baby who is growing so well," she said.

"It all evens out," McPhee added at the time. "They all end up in the same place, but right now he's a little bit ahead of the curve. It's super fun to be like, 'Oh, he's advanced.' But really you know that your baby is just the same as any other baby."

Last month, McPhee shared a sweet picture of her husband spending time with Rennie on her Instagram Story. She wrote alongside the candid shot, "My boys."

Foster is "always walking into a room saying, 'Where's my baby? Where's our baby?" McPhee told PEOPLE back in May. "He wants to hold the baby all the time, and be around the baby."
