Gigi Hadid And Zayn Malik Are Having A Baby: Source

It's been a big year for One Direction fans. Not only have rumors been swirling about a possible reunion, at least to celebrate the band's tenth anniversary in the summer, but now there's baby news on the horizon as well, according to TMZ.

Model Gigi Hadid and singer Zayn Malik have had an on-again, off-again relationship since 2015.

The couple confirmed their most recent on-again status in February, when Gigi posted a sweet picture of Zayn for Valentine's Day, but they had been spotted together fueling reunion rumors since December.

Gigi recently celebrated her 25th birthday while in lockdown on her family's farm in Pennsylvania.

Photos shared from the occasion confirm that Zayn is there with them, which would definitely make sense given the latest reports that Gigi is 20 weeks pregnant.

While the couple have not confirmed the news themselves, some eagle-eyed fans have spotted what they think were clues.

Some fans think the pink and blue strings attached to Gigi's birthday balloons may have hinted at a gender reveal.

A source told Entertainment Tonight that "Once Gigi and Zayn got back together at the end of last year, it was like they never skipped a beat and knew what they had was special."

"The couple and their families are overjoyed."

While we're eagerly awaiting confirmation from the couple, fans are pretty excited for the third One Direction baby (Zayn's former bandmate Louis Tomlinson has a four-year-old son, and Liam Payne has a three-year-old son). Maybe a band reunion in the form of a playdate is on the horizon!

Congratulations to Zayn and Gigi!
