Representatives for Gigi and Zayn did not immediately return HuffPost’s request for confirmation.
Last week, the couple celebrated Gigi’s 25th birthday with her sister Bella Hadid and a handful of others, and she thanked her “quarantine family” ― including Zayn ― for making the day so special.
“I am grateful and lucky that my family and friends ― near and far ― are healthy and safe, and although I missed loved ones I wish I could have celebrated with, know that these times will make us even more grateful for togetherness to be had in the future!” she wrote on Instagram, sharing images from her family’s farm in Pennsylvania, where they are isolating.
After an on-again, off-again relationship in the years that followed, they reportedly got back together towards the end of last year.
Gigi erased any doubt about those rumours with a sweet Instagram post about the Like I Would singer to commemorate Valentine’s Day.
Fans went wild over the pregnancy reports, with “gigi” and “zigi” quickly soaring to the top of Twitter’s trending topics late on Tuesday night.
Zayn is the third member of One Direction to become a father, with Louis Tomlinson and Liam Payne already parents to their respective sons, Freddie and Bear.
