Elsie Hewitt flaunted her sexy swim style less than a week before revealing that she is expecting her first baby with boyfriend Pete Davidson.

“Bydee_aus mirror pics 4 u 👙,” Hewitt, 29, wrote via Instagram on Sunday, July 13.

In the snaps, Hewitt wore a crimson two-piece with a New York Yankees cap and a delicate pearl choker necklace.

Hewitt confirmed just three days later that she is pregnant.

“Welp, now everyone knows we had sex,” the British model wrote via Instagram on Wednesday, July 16, sharing maternity photos with Davidson, 31, and footage from an ultrasound appointment.

Davidson has yet to publicly address Hewitt’s pregnancy, though a source told Us Weekly how the Saturday Night Live alum is feeling.

“He is excited about this next chapter,” the insider exclusively shared with Us on Wednesday.

Davidson has long been hopeful that his future would include parenthood.

“I’m definitely a family guy. My favorite thing ever, which I have yet to achieve, I wanna have a kid. That’s like, my dream,” Davidson said on a 2022 episode of Kevin Hart’s Hart to Heart. “It’s like, super corny, [but] it would be so fun. Dress up the little dude.”

He added, “I’m so excited for that chapter. That’s kind of what I’m just preparing for now, is just trying to be as good as a dude, develop and get better so when that happens it’s just easier. … Since my dad died, I was like, ‘Oh, I can’t wait to have a kid.’”

Davidson publicly confirmed his relationship with Hewitt in March, making their red carpet debut two months later at the Endometriosis Foundation of America’s Blossom Ball.

“He is so incredible,” Hewitt told People on the red carpet in May. “Honestly, best person I’ve ever met, and I’m so grateful that he’s here tonight. It was just really important to both of us to come here and support the [Endometriosis Foundation of America] and keep helping, spreading the word and educating people.”
