Sebastian Stan and Annabelle Wallis went out together in matching outfits months after sparking romance speculations.

People reported that eyewitnesses saw the 40-year-old actor and the 38-year-old actress holding hands on a Wednesday stroll in New York City, adding that the outing has marked a rare appearance for the pair.

For the day trip, Stan and Wallis are said to have worn matching black outfits. They also had her dog, Zeus, with them, with the magazine noting that the actor was holding the leash.

The Marvel actor and the “Peaky Blinders” actress reportedly first sparked romance speculations earlier in May. As noted, it came after they attended Robert Pattinson’s 36th birthday in the Big Apple, and photos of them together emerged on media platforms.

People said in the same report that one of the shots photographer Myles Hendrik shared from the party at the time shows Annabelle Wallis and Sebastian Stan spending time together. It added that the actress could be seen pressing her lips against his bottom lip, seemingly sparking the speculations.

But, reports noted that neither of the two celebrities has addressed the photo. They have also since maintained their silence about the status of their relationship.

Annabelle Wallis and Sebastian Stan were seemingly last seen in August when Us Weekly said they were photographed in Greece.

At the time, the outlet reported that the “Captain America: The Winter Soldier” actor was also with pals in the country to celebrate his 40th birthday.

The publication then described the looks the two celebrities had during the said outing in Greece. It noted that the “Malignant” actress donned a coral dress and black sweater, while Stan sported a salmon and eggshell-colored bowling shirt with a lapel collar.

Us Weekly also recalled in its report, published on August 14, that Wallis and the “Avengers: Infinity War” actor were seen together the month prior, citing photos obtained and shared by the Daily Mail.

In the report from July, the Daily Mail said Sebastian Stan and Annabelle Wallis enjoyed lunch together in Manhattan’s West Village.

It noted that the two celebrities were also seen strolling with their arms wrapped around each other at one point in the outing, adding that they were with the actress’s rescue dog, as well.

Stan and Wallis had just gotten out of their respective relationships prior to their joint outings.

A previous report from Entertainment Tonight stated that the actress had split from Chris Pine after nearly four years of dating, with the confirmation emerging in March. 

As for the “Once Upon A Time” actor, the outlet recalled that he was most recently in a relationship with Alejandra Onieva, whom he started dating in 2020.
