For his first public event since his breakup with Taylor Swift, Joe Alwyn showed up to the French Riviera—in style.

The English actor attended the Celine dinner at Hotel du Cap-Eden-Roc in the South of France, hosted by the brand’s artistic director Hedi Slimane during the 2023 Cannes Film Festival.

The Favorite star sported a black, subtly pinstriped suit over a silky salmon button-down shirt, left open to reveal his white tank top. Alwyn accessorized his look with a thin gold chain necklace, chic black shades and classic black dress shoes.

Faces and friends of the house, including Kaia Gerber, BLACKPINK’s Lisa, rapper Future and more were in attendance. Wunderhorse front man Jacob Slater performed live for the A-list guests following the dinner.

In April, Entertainment Tonight reported Swift and Alwyn called it quits in March, in what was allegedly an amicable split. According to a source, the relationship “had just run its course,” and was “not dramatic.”

Swift, 33, and Alwyn, 32, began dating in 2016, and though they’ve managed to keep much of their relationship private, it’s been thought that the two were still going strong until fans began to worry Alwyn hadn’t been there to support Swift on her world tour.

Looking for clues, fans believed Swift dropped a hint about the breakup at her March 31 concert. Swift performed in Arlington, Texas and replaced the romantic song “Invisible String” with the breakup song, “The 1.” It includes the lyrics, “But we were something don’t you think so?” and “If my wishes came true, it would have been you.”

Just about a month after the news broke that Swift and Alwyn had split after six years of dating, the Grammy Award-winner seems to be moving on. According to The Sun, the Midnights artist is “madly in love” with the lead vocalist and rhythm guitarist of the English pop rock band, The 1975, Matty Healy. The pair have maintained a close friendship since 2014, and while they briefly dated back in the day, the musicians have continued to collaborate.

Alwyn, who Swift’s friends unfollowed on Instagram hinting that the British actor may have done Swift dirty, is reportedly upset by these developments with a source telling Daily Mail“Joe feels slighted and is distraught after seeing her budding relationship with Matt, but is doing his best to keep busy and focus on himself.”

“Joe was aware that Taylor and Matt were making music together and collaborating,” they continued. “She told him that they had become friends and he trusted her.” However, the insider denied there was any romantic “overlap” between Healy and Alwyn in Swift’s life.

Sources aside, while performing in Massachusetts on Saturday night, Swift told fans: “I’ve just never been this happy in my life, in all aspects of my, life ever. And I just want to thank you for being a part of that.”

“It’s not just the tour,” she added. “I just sort of feel like my life finally feels like it makes sense.”
