Katharine McPhee has been enjoying her life as a new mom.

The "American Idol" alum, 36, and her husband David Foster, 71, announced in February that they’d welcomed their first child together.

"It just feels so natural," the singer/actress told People magazine on Friday. "I’ve had a really good baby; he’s been so good. I’m so in love!"

And when it comes to her post-pregnancy body, the star insisted she’s not stressing over it.

"I thought I would have this pressure [to bounce back] but I’ve just been so grateful and happy that I’ve had a healthy baby and I’ve felt really good emotionally and physically," McPhee explained. "I’m so happy that I don’t have this crazy pressure yet to fit into whatever jeans I have in my closet."

"I don’t even think about them right now!" McPhee continued. "In my everyday life, I would have an event coming up or need to work out, and it’s just really nice to have a break and be happy where I am."

McPhee said that motherhood has also given her plenty of time to enjoy her family, which is more important than squeezing into any pair of jeans.

"I’m up at 5 a.m. with him and we listen to his dad’s piano album ["Eleven Words"] and we have our quiet time," she said. "And at night before we put him in his room, it’s just the three of us in bed. We take lots of pictures! It’s really sweet."

Recently, McPhee made an appearance on "Today with Hoda and Jenna" where she revealed the baby’s name: Rennie David Foster.

"We picked Rennie because I had actually been in labor for a while, we didn’t have a name picked out," she recalled. "We had a couple names, but my husband was on a text chain with his sisters and one of his sisters suggested an old family name."

McPhee said that the name had belonged to Foster’s great-grandfather and great uncle, so "it has a long history in his family."

"My husband said, ‘Hi, Ren Foster,’ so we said, ‘That’s a good name. That’s a strong name,’" the star said.

Things seem to be going well for the new mom, as she said motherhood has been "the sweetest" and "the best" experience.

"I’m in heaven," she added. "It’s really been amazing."

She also joked that her husband is going to "kill" her for sharing the baby's name publicly.

McPhee and Foster, who also has five children from previous relationships, tied the knot at a church in London in June 2019. The couple first met in 2006 when McPhee was a contestant on the fifth season of "American Idol" and Foster was a mentor on the singing competition series.

Foster proposed to McPhee in July 2017 with a huge emerald diamond ring while the couple was on vacation in Italy.
