Jesse McCartney and Katie Peterson are set to welcome their first child.
On Friday, the 37-year-old singer and his wife took to Instagram to announce that Katie is pregnant, with a heartwarming photoshoot of the pair showing off sonograms of their little bun in the oven.
The lovebirds shared that their unborn child will be arriving on August 8, 2025, meaning Katie is around 15 weeks along as of mid-February.
‘Our lil Valentine arriving 8/8. xo, JK,’ the penned in the caption as a nod to the holiday.
In the final slide, fans got a hint at the baby’s name — though they did not reveal the sex — as the pair shared a snap of two hearts that read ‘Baby Mac’ and ‘August 2025’, with the ultrasound image in the center surrounded by roses.
And we also saw the duo basking in a joyful moment, sporting matching black satin pajamas that respectively read ‘mom’ and ‘dad.’

McCartney and the Step Up Revolution star exchanged vows back in 2021 at a rustic inspired ceremony held in Carmel, California after seven years of dating in the public eye.
In April of 2024, McCartney told Today that he and his wife were ‘trying’ to conceive while discussing the inspiration for his recent hit Make a Baby – featuring rapper Yung Gravy.
‘The truth is that it takes time and you have to be ready to go at all times. It’s not necessarily always as sexy as people talk about,’ he told the outlet.
The vocalist also quipped that he would need to reconsider his preferred genre of music and what tracks he released to make his future child ‘super proud.’
He added at the time, ‘I’m still thinking about that and what that looks like. I mean, first I need to make a baby.
‘And then I need to start thinking about what kind of music I want to write for the baby. Who knows, maybe I’ll start making lullaby, children’s albums for the next few years,’ the star teased.
