The couple began dating in 2015 and announced their split in 2018, but rekindled their relationship at the end of 2019. They have kept their relationship pretty private, and they are now embarking on a new journey together as parents.

Gigi celebrated her 25th birthday with Zayn this weekend.

The model and her beau have been social distancing together at her family's farm in Pennsylvania, and that's where she celebrated her 25th birthday, which was on April 23. She shared a video with her model sister, Bella Hadid, and her man on Saturday, April 25, and they're adorably posing with number balloons with her age.

The birthday party could have also moonlighted as a gender reveal.

Fans began to notice that the birthday party might have doubled as a gender reveal party. The blue and pink strings on her balloons made some believe that perhaps the couple also found out the sex of their baby at Gigi's 25th birthday bash.

She shared a post with multiple photos from the celebration, and one of them was a pic of her hugging her man. She was holding only the "2" balloon with a blue string. Could this mean that the singer and the model are expecting a boy?

The gift bags seemed to give away some clues.

Bella hared some photos from the celebration that showed her big sister's presents. Some of them were gifted to her in Baby Shark bags as well as a pink bag with floral designs that said "Hello Little One" on the front. That's an odd choice for a 25th birthday party.

She was spotted at an obstetrician-gynecologist's office.

Fans went as far back as February to find this photo of Gigi at a doctor's office. Gigi and her sister posed for a pic with Dr. Sherry Ross, who is an obstetrician-gynecologist in California. They also noticed that the doctor followed Zayn on Twitter, even though the singer has no photos of Gigi on his page.

Zayn and Gigi have a long history together.

Zayn and Gigi were first linked together in 2015, soon after his departure from the boy band One Direction. The couple spent a lot of time together between New York City and California and seemed inseparable. They later announced their split in 2018, and she even dated Bachelorette star Tyler Cameron during the breakup.

She confirmed they were back together on Valentine's Day 2020.

After she split from the reality TV star, there were rumors swirling that  she had rekindled her romance with Zayn by the end of 2019. The two were spotted spending time together in NYC in January 2020. She confirmed they were back together by posting a photo of him on Valentine's Day in February 2020. "HEY VALENTINE Z on the farm ♡ Dec 2019," she shared on her photography Instagram account.
