Shawn Mendes and Camila Cabello fuel dating rumors in matching outfits

That’s one stylish duet.

Shawn Mendes and Camila Cabello celebrated the holiday weekend together in a series of perfectly coordinated outfits, fueling rumors that the “Señorita” collaborators are dating.

Last Wednesday night, the two were snapped heading to 20-year-old Mendes’ West Hollywood home; the “In My Blood” singer, 20, wore a black-and-white striped silk shirt and black jeans, while the “Havana” hitmaker, 22, matched in a strappy, backless black jumpsuit and a black quilted Chanel “Gabrielle” backpack ($4,100), which Mendes gamely carried for her as they strolled along hand in hand.

On July 4, the duo partied poolside at the Red White & Bootsy bash at Nobu Malibu, where Cabello chose a white Free People “Cruel Intentions” ruffled minidress ($148) and Mendes coordinated in crisp white jeans and a short-sleeved, semi-sheer button-up.

And on Sunday, the pair headed to brunch in even more likeminded looks, with Mendes in all-black Nike athleisure and Cabello following suit in a white cami, black hoodie, side-striped leggings and black Adidas Ultraboost sneakers ($180).

Just last month, Cabello reportedly parted ways with boyfriend Matthew Hussey after almost a year and a half together. Mendes, meanwhile, was most recently linked to Hailey Baldwin, with whom he attended the 2018 Met Gala — shortly before she got back together with (and then married) Justin Bieber.
