Gigi and Bella Hadid looked like very close siblings as they posed on the red carpet side by side.
The model pair were attending the Pencils of Promise event in New York, and looked super close as they posed for the cameras.
It looked like the stunning sisters were far from sibling rivals as they cuddled up together and held hands before heading into the event.
But while their close bond was obvious on the night, the Hadid sisters couldn't have been further apart when it came to their outfit choices.
While 20-year-old Gigi went for a dressed-down look in ripped jeans, teamed up with a jersey t-shirt and long coat, younger sister Bella upped the glamour in a black mini dress.
The 19-year-old model finished the look of with a super tight bun, while sister Gigi even kept things relaxed when it came to her hair, and wore it down.
Her laid-back look was a far cry from a recent Vogue photo shoot with boyfriend Zayn Malik , which saw Gigi adopt some pretty acrobatic poses.
The sisters were also joined by Puerto Rican model Joan Smalls, who dazzled in a navy, silk dress paired with some sunny yellow heels, which were identical to Gigi's.
All three looked to be sharing a giggle at something as they worked the cameras.
While Gigi is well and truly loved up with Zayn Malik, Bella has recently packed on the PDA with boyfriend, The Weekend.
The pair were spotted looking very loved up at The Daily Front Row's Fashion Awards last month, where Bella beat her sister Gigi to Model Of The Year at the fashion bash.
