No bathing suits? No problem!

Shawn Mendes and his possible new girlfriend, Charlie Travers, wore only their underwear during what appeared to be an impromptu beach date on Wednesday.

The “In My Blood” singer was photographed stripping down to his Calvins, which matched the TV personality’s black bra top.

Travers also sported a lacy thong while relaxing with Mendes in the sand in Malibu, Calif., accessorizing with hoops, a gold cuff on her arm and a necklace.

The rumored couple, both of whom had sweaters on hand, ultimately left the beach in jeans.

They first made headlines for cuddling up at a West Hollywood restaurant, where Travers, 37, was seen putting her arm around Mendes, 25, on Tuesday in a photo obtained by TMZ.

The former “Big Brother UK” contestant also cozied up to the Grammy nominee at the beach, putting her hands in his hair and on his back during their fun in the sun.

His rep did not respond to Page Six’s request for comment on the status of their relationship.

Mendes was last in an on-again, off-again romance with his “Señorita” collaborator, Camila Cabello.

The former couple started dating in July 2019 and quarantined together during the COVID-19 pandemic before calling it quits in November 2021.

“Hey guys, we’ve decided to end our romantic relationship but our love for one another as humans is stronger than ever,” the exes wrote in a joint Instagram statement at the time.

“We started our relationship as best friends and will continue to be best friends.”

However, Mendes and Cabello, 26, reunited at Coachella this April and were caught on camera locking lips.

Despite multiple ensuing date nights, the “I Know What You Did Last Summer” singers have not been spotted getting touchy-feely since attending Taylor Swift’s Eras Tour together in May.

People reported in June that the former Fifth Harmony member was back on the dating scene, but she has yet to go public with a new partner.
