Harry Styles and Emily Ratajkowski are getting close.
The musician, 29, and the model and actress, 31, were spotted kissing in Tokyo in photographs and video obtained by The Daily Mail.
Now, a source tells PEOPLE that "Harry and Emily know each other," noting, "They have been friendly for a while."
The insider adds that Ratajkowski is also "friendly" with Olivia Wilde — Styles' ex. That relationship ended in November.
In the photos and video obtained by The Daily Mail, Styles and Ratajkowski can be seen sharing several kisses with each other.
The "As It Was" singer was captured wearing a white shirt with a black jacket and matching pants, while the High Low with EmRata podcast host was seen sporting a pink and black jacket and a long black skirt.
Styles was in Japan performing as part of his Love on Tour concert series, which will pick back up in Denmark in May after an extended break.
A representative for Ratajkowski did not immediately respond to PEOPLE's request for comment on Saturday. A representative for Styles, meanwhile, had no comment when reached by PEOPLE.
Multiple sources confirmed to PEOPLE in November that Wilde, 39, and Styles were "taking a break" from their relationship after nearly two years together, noting the "very amicable decision" came amid Styles' continuing touring schedule and Wilde's focus on her children and work in Los Angeles.
A source later told PEOPLE of Wilde, "She and Harry are good friends, there's no animosity whatsoever."
The mother of two and Styles, who met on the set of their film Don't Worry Darling back in September 2020, first stepped out as a couple as they were photographed holding hands while attending a wedding together in January 2021.
Ratajkowski, meanwhile, has recently been linked to Pete Davidson and Eric Andre after her divorce from film producer Sebastian Bear-McClard in 2022. (Together, the pair share 2-year-old son Sylvester Apollo Bear.)
