Jennifer Lopez risked a wardrobe malfunction during a flirty “Office Romance” scene with her co-star Brett Goldstein.

The actress, who portrays Jackie Cruz in the film, left little to the imagination in a brown string bikini while lounging on the beach with Goldstein’s character, Daniel Blanchflower.

Lopez was seen retying one of her bottom strings before brushing sand off her behind.

“My god, I have so much sand in my butt!” Lopez, 56, said.

“If you turn me over you could tell time,” she quipped.

In the Netflix rom-com, Lopez’s character portrays an airline CEO and pilot who falls for Blanchflower, her company’s new in-house lawyer.

The duo had “undeniable chemistry” both on and off the screen, but an insider told Page Six they “kept things professional” while filming.

“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 source explained.

The source added, “Everyone saw them getting very cozy together at the wrap party and it was obvious they were into each other.”

The co-stars even took their friendship to Broadway to watch “Oh, Mary!” in New York City together.

Lopez gushed over her “great chemistry” with Goldstein while on the 2026 Netflix Upfront red carpet in May.

“It just grew as we did the film together,” she told People. “I expected more of a rough guy, but you get this kind, gentle but also very smart person that is so charming. That was a surprise, I think.”

Lopez, however, shut down dating rumors with the “Ted Lasso” star during an appearance on “Today” earlier this month.

“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 “Enough” star said in response to Savannah Guthrie. “It happens all the time. Doesn’t make it true.”

“OK, so you’re not dating in real life?” Guthrie asked, as Lopez responded, “Not dating.”
