Selena Gomez looked relaxed and well-rested when she left New York just a few days after she put her relationship with ex-boyfriend Justin Bieber completely behind her.

On Thursday, Gomez was spotted at John F. Kennedy airport boarding a plane two days after her guest appearance on "The Tonight Show Starring Jimmy Fallon" to promote her new movie, "The Dead Don't Die." In photos obtained by Daily Mail, the singer-actress went makeup-free and donned a casual look for her flight.

Gomez looked comfortable in a mint-colored sweatsuit, which she paired with white sneakers. The former Disney star was also photographed sporting dark sunglasses and carrying a tan teddy coat as she made her way through the airport. Gomez let her wavy brunette locks flow freely around her shoulders.

Over the past week, Gomez has been busy with the promotions of the zombie fantasy movie, "The Dead Don't Die," which also stars Adam Driver, Bill Murray, Tilda Swinton, Steve Buscemi and Chloe Sevigny, among many others. In the flick, Gomez plays the role of Zoe, a young woman traveling with Jack (Austin Butler) and Zach (Luka Sabbat).

"The Dead Don't Die" hits theaters in the U.S. Friday, June 14.

Meanwhile, Gomez's latest sighting comes less than a week since eagle-eyed fans discovered that her last Instagram post about Bieber was missing from her account.

The "Hands to Myself" has apparently decided to erase all traces of her relationship with her ex-boyfriend by deleting the birthday tribute she posted for him in March 2018. In the post, Gomez shared a photo of herself smiling while appearing to be showing off a polaroid picture of Bieber.

Gomez and Bieber briefly got back together in late 2017, but they once again split at the end of March. The "Love Yourself" crooner then got back together with Hailey Baldwin, whom he married in September last year.

While Gomez and Bieber didn't open up about their final breakup, a source told People in July 2018, around the time Bieber got engaged with Baldwin, that it had been hard for the two singers to make their relationship work due to all their "baggage."

“Their relationship was always very complex and complicated," the insider dished. "It was just too much baggage. It was like their past tainted everything. It wasn’t possible for them to have a future.”
