The blonde was posing for the famous LOVE advent calendar, that features a different A-lister each day.
But it wasn’t her skimpy red two piece that got people talking – instead it was her armpits.
Gigi appears to show off armpit stubble as she poses in bright work out gear for the video.
Fans were instantly divided over the look, and took to Instagram in their droves to comment.
“Babe. Plus bonus respect for keeping the pit hair real,” one wrote.
Another added: “Idk why but the fact that she didn’t shave her armpits makes this so real and natural and I love that.”

Yet some commented that Zayn Malik’s girlfriend looked “manly” after flaunting her underarms.
“Her armpit hair was too distracting for me to watch the video,” a commenter wrote. “That should of been shaved. This magazine should of known this before shooting and releasing this video. Just not a clean look!”
Others said that it wasn’t hair at all, instead just fluff from the jumper she wears at the start at the video.
“Dude this is just jumper fluff right,” one said while another added: “It’s not her armpit hair, it comes from the sweater she wears earlier.”
Gigi said of her advent clip: “I love seeing everyone else’s videos. It’s celebratory of epic human beings and always pushes boundaries.
“The fashion circle is a family, so the Love Advent kind of feels like a Holiday Year Book in a way. Headmaster Grand style.”
