Jennifer Aniston had a special someone by her side on her big night.

The actress was in New York City on Tuesday, Sept. 9, to celebrate the fourth season of The Morning Show, and her boyfriend Jim Curtis joined her at the Museum of Modern Art for the premiere.

Aniston stepped out in a sleek black dress cinched in the center to accentuate her figure, as she posed with costars Reese Witherspoon, Billy Crudup and Mark Duplass.

Curtis was spotted smiling and standing along the side of the red carpet in casual all-black attire that included a sweater and casual black slacks.

In a Sept. 7 post, the actress shared a carousel of 18 photos from the last few months, writing in the caption, “Thank you summer ☀️❤️🙏🏼.”

Among the photos she included was a sunset shot that featured the back of a mystery man’s head, which fans suspected she took while standing behind Curtis.

Though she didn’t tag Curtis in the post, many fans took the inclusion of the photo as the soft-launch of their relationship.

The pair have been dating for a few months, a source previously told PEOPLE.

In July, Aniston was spotted enjoying a yacht trip off the coast of Mallorca — where she was joined by friends including Jason Bateman and his wife Amanda Anka — and Curtis was with her for the vacation.

It was the first time they were seen together, and in one photo obtained by PEOPLE, they appeared to be holding hands.

A source told PEOPLE at the time that they are “casually dating and having fun” and have been “seeing each other for a few months now.”

“They were introduced by a friend and started out as friends. Jen had read his book and was familiar with his work,” the source said, referring to Curtis’ career as an author and life coach. “He’s very different from anyone she’s dated before.”

After a period of not dating “seriously,” things feel “different” for Aniston with Curtis, a source said.

In August, another source told PEOPLE that Curtis is “amazing to be around” and the actress’ “close friends love him.”

“He has this really calm and secure energy. Jen loves it,” the source said. “He feels very safe for her.”

It’s still “early” for the couple, the source noted, but things are going really well so far.

The hypnotherapist has “helped her turn inwards and slow down a bit” and is teaching her to “really appreciate and feel proud of everything she’s built,” the source said.

The Morning Show season 4 premieres Wednesday, Sept. 17 on Apple TV+.
