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.

Even though Shawn Mendes shut down rumors that he’s dating Camila Cabello over the weekend, the two seemed to be wearing matching outfits and were spotted holding hands and giggling again while out and about on July 7th.

The two were snapped heading to 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 and Mendes coordinated in crisp white jeans and a short-sleeved, semi-sheer button-up.
