They are the sisters who have dominated New York Fashion Week (Kendall, who?) – and Gigi and Bella Hadid certainly turned heads at the Tommy Hilfiger show.
Taking to the catwalk for the US designer's grand finale yesterday, the duo donned teeny-tiny swimwear – which showed off plenty of toned bum.
Yup, we're having major bikini-bod envy.
Gigi, 20, and Bella, 18, held hands as they splashed through a dramatic water feature (all part of Hilfiger's beach-inspired set), even leaning in for a sisterly kiss at one stage.
For her final look, the elder Ms Hadid wore a striking patchwork print two-piece with beaded lattice detailing on the front (although – hello, tan-marks!).
Meanwhile, teenager Bella had on a Rasta-style multi-coloured string vest , which she wore over an equally bright and brilliant string bikini.
Joining them on the catwalk was the likes of Stella Maxwell, Miley Cyrus's rumoured girlfriend, and Hailey Baldwin – also very part of Hollywood's latest Jenner-Hadid dominated brat pack.
And watching from the surrounding Caribbean beach huts (we're loving Hilfiger's S/S '16 vibes) was Joe Jonas, 26, the musician beau of Gigi.
Other famous faces included Victoria's Secret star Behati Prinsloo, as well as Sofia Richie, the daughter of singer Lionel and a model in her own right, and actress Suki Waterhouse.
Afterwards on Instagram, Gigi had shared a snap of the closing segment with her 6.1million followers.
"Finale gooaalllssss," she said. "Love these girls & so honored to be a part of this show."
It's been a seriously busy NYFW for the Hadid duo: both girls had just the day before strolled down the runway at DvF's Spring '16 show.
And after dominating at Tommy Hilfiger, they then hopped over to Jeremy Scott where they were on hand to debut the label's retro, Mad Men-style outfits.
