Hailee Steinfeld and Niall Horan have fueled rumors they are dating after being spotted at a Backstreet Boys concert in Las Vegas on Saturday night.
Us Weekly reports Hailee and Niall were dancing and singing along at the Planet Hollywood Casino and Resort.
The pair were also seen later in the night at XS Nightclub and watched Diplo.
Fans first began speculating that Horan and Steinfeld were dating after they were spotted at London’s West End production of Hamilton on January 2.
A week later, Horan attended a birthday party for the “Starving” songstress’ older brother.
