It’ll be a girl!

Arie Luyendyk Jr. and Lauren Burnham have revealed the sex of their unborn baby.

The Bachelor star, 37, shared the couple’s big news on Instagram Friday afternoon.

“I think, to be honest, in the beginning, we were both hoping that we were having a girl,” Burnham, 27, told Us Weekly.

“We actually did the early gender test online, so we took our test at 10 weeks,” Burnham told the outlet. “We got the results back from that, and it was that we were having a boy.”

The doctor then encouraged the engaged couple to get an ultrasound five weeks later and that’s when they found out they were actually having a girl. BurnhamArie Luyendyk/Instagram

He added that they were “Packing for Hawaii!!!!”
