Exclusive | Jennifer Lopez and Brett Goldstein had secret fling while filming ‘Office Romance’ –

Jennifer Lopez and Brett Goldstein went from hot and heavy to just friends.

A source exclusively told Page Six that Lopez and Goldstein – who are co-starring in the upcoming Netflix movie “Office Romance” — “kept things professional on set while filming but their chemistry was undeniable.”

“They tried to keep things low-key during the months while filming but flirted here and there on set, and they definitely had a strong connection,” the insider said. “Everyone saw them getting very cozy together at the wrap party and it was obvious they were into each other.”

According to the source, Lopez, 56, and Goldstein, 45, enjoyed a night out together in early 2025 when they attended the Broadway play Oh, Mary! in New York City.

“Once filming wrapped, they were free to take things further and dated for quite some time,” the insider said.

According to the source, however, the relationship eventually lost momentum once filming wrapped.

“They liked spending time together and Brett made her happy,” the source explained. “But things just sort of fizzled out between them since last year.”

The source stressed that there is no animosity between the two and says they remain on good terms.

“There’s no bad blood but it just kind of came to a lull. They have a good friendship but in terms of romantic chemistry, that ship has sort of sailed,” the insider said.

The “Hustlers” star and the “Ted Lasso” alum “dated for a bit and had a really strong physical attraction toward one another. Nothing major happened, they just felt like they were better off friends than anything else.”

Representatives for Lopez and Goldstein did not immediately return Page Six’s requests for comment.

News of the Netflix romantic comedy broke in September 2024, with Goldstein set to star opposite Lopez.

Social media users were quick to point out Goldstein’s longtime crush on Lopez, which he has frequently vocalized on his “Films to Buried With” podcast.

One fan posted a clip via X of Goldstein gushing over the actress’ appearance in “The Hustlers” in a July 2018 episode.

“F–king hell. 50!” the comedian exclaimed of Lopez’s age at the time. “She’s 50. I love her.”

He went on to express jealousy toward one of her female co-stars during a scene when Lopez wore a fur coat while hugging her.

“I’ve never wanted to be cuddled more,” Goldstein said. “That is one of the best cuddles. … give me one of your special cuddles.”

As previously reported, the singer shut down romance rumors with Goldstein in an awkward live TV moment during Tuesday’s Today Show.

Host Savannah Guthrie asked the “Office Romance” co-stars whether speculation about their offscreen chemistry is true.

“There’s never a time when I’m seen with somebody or working with somebody where they don’t try to put me with the person,” the “Let’s Get Loud” hitmaker replied.

However, Guthrie wasn’t satisfied with the pair’s responses to her question, telling Lopez specifically that she circled around the question.

“OK, but I’ll just say, because I’m me and you know me, that was not an answer,” she said.

“Not dating,” Lopez said as Goldstein added, “Correct.”
