Friends? Jacob Elordi Kisses Zendaya in New York City

Zendaya, 23, and “Euphoria” co-star Jacob Elordi, 22, are redefining what it means to be best friends!

On Monday, Jacob was seen kissing Zendaya on the head as she checked her phone on a bench in New York City.

A source told E! News, “They were showing each other things on their phones and laughing. She seemed to be really enjoy being with him. At one point he reached over and kissed her on the forehead. She had a big smile on her face and was very comfortable with them.”

The two were photographed smiling while enjoying the day together, picking up green drinks and stopping at Strand Book Store. The eyewitness went on, “They walked in sync and looked happy together. Zendaya couldn’t help but break into a big smile from time to time… Jacob hailed a cab for them and got the door for Zendaya. She hopped in and looked over at him with a big smile again.”

Just days ago, Zendaya referred to Jacob as her “best friend” as she presented him with the Rising Star honor at the American Australian Association Arts Awards in New York.

Jacob recently shut down the dating rumors to GQ Australia magazine. He said, “She’s like a sister to me.”

He added, “She’s super dope to work with. She’s an incredible artist and a very caring person to all of us. But we’re all really close. There is not one weak link in that show. We’ve spent so much time together and everyone is just so cool to work with.”

Romance rumors have been swirling about Zendaya and Jacob since summer after they were seen vacationing in Greece together.

Zendaya is no stranger to dating rumors — she has also been linked to “Spider-Man: Homecoming” actor Tom Holland and football star Odell Beckham Jr. She insisted that she hasn’t dated either.

In 2016, “Extra” spoke with Zendaya, who addressed rumors that she was dating Beckham Jr. after they were spotted at a Knicks game. She said it was just a coincidence, saying, “It happens all the time. Literally if I show up anywhere with anyone that automatically happens. It’s funny because I didn’t go there with him, actually; he just happened to be there as well. I didn’t know he was going to be there. Immediately when I saw him I was like, ‘Oh, dang it!’”
