Jordin Sparks can’t wait to be a mom, but she’s prepared for her son on the way to be a daddy’s boy.

“I was talking to [husband Dana Isaiah] the other day [and] I was like, ‘I just have a feeling you guys are gonna conspire against me,’ ” the American Idol alum, 28, jokes to PEOPLE Now.

She adds with a laugh, “I feel like it’s gonna be one of those things where it’s like, ‘Don’t you tell your mother about this.’ And then I’m gonna have to find out a week later about something.”

Sparks, a longtime Operation Smile ambassador, was in New York for her partnership with the “Smile with Lay’s” campaign, which benefits the cleft lip and palate charity. She helped launch The Lay’s Smiles Experience — a three-day pop-up in the Big Apple — earlier this week. Starting this month, purchases of specially designed Lay’s potato chip bags featuring smiles will result in a donation for Operation Smile.

Sparks’ workout routine has changed quite a bit since finding out she was expecting — namely, whether she joins her model and fitness-enthusiast husband at the gym depends on how she’s feeling on any particular day.

“We would go to the gym maybe three or four times a week … and then the pregnancy changed everything because I was so tired,” she recalls. “The first trimester, I slept the entire time. Then the second trimester hit and I had more energy, and I do have more energy [now].”

“So there are days when I’m like, ‘Okay, babe, let’s go, let’s get this going, it’ll be great, I’ll go with you,’ ” she continues. “And then there are a lot of days where I’m like, ‘I’ll see you when you get home.’ ”

After a whirlwind courtship following their first meeting in February 2017, Sparks and Isaiah tied the knot in a secret ceremony on July 16, eloping during a Hawaiian getaway with their best friends. They confirmed exclusively to PEOPLE in November that they were expecting their first child.

But the “No Air” singer wasn’t looking for love — love found her. As she explains to PEOPLE Now, “I have so much love in my life already — my nieces, my family, my friends — that I was just like, ‘You know what? I’m okay. If [a romantic interest] shows up, then it shows up.’ ”

“And then it showed up, and I was not expecting it,” Sparks continues of husband Isaiah, 25. “We were both really caught by surprise … The thing that you hear sometimes — ‘When you’re least looking for it, that’s when it finds you’ — it actually did.”
