Jennifer Lopez became the center of a blizzard of plastic surgery speculation when she attended the premiere of her new film Office Romance on Tuesday.

The 56-year-old's red carpet appearance was a feast for the eyes, from her luminously youthful complexion to her gym-sculpted dancer's physique.

However, it was the generous helping of cleavage she served up in her sheer strapless dress that left social media users scratching their heads.

'Are those new? Or have I just never noticed,' one observer marveled on Reddit, prompting another to reply: 'Wondering the same thing myself.'

A third remarked: 'Her boobs looking anything but natural,' while a fourth sniggered that she had acquired 'Bolt-ons,' and a fifth joked: 'But can they sing?'

The Daily Mail has contacted Lopez's representative for comment. 

Her look was so arresting that even a decided non-fan was forced to concede: 'I can’t stand the woman but man she is freaking gorgeous. New boobies though, right?' 

'She got new boobies,' wrote a viewer, to which another replied: 'literally my brain: “where did those come from?” She looking fly tho, nowhere near 56.'

Another wondered: 'At what time in your life does one decide "OK, that was my last boob tune-up, after this I'm just letting them age naturally."' 

Lopez posed at the premiere on the arm of her dashing co-star Brett Goldstein, hours after they addressed the dating rumors that have been trailing them for months.

That morning, Savannah Guthrie asked about the conjecture to their faces while they were promoting their movie on the Today show.

After a beat, Lopez said: '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.' 

'I think if you stand near her, that's what happens,' Goldstein said, springing to her defense. 'That's why I've been standing so close this whole time.' 

'Okay, but I'll just say, because I'm me and you know me: that was not an answer,' said Guthrie, over Lopez's protest: 'It was an answer!'

After a bit more back-and-forth, Guthrie was finally able to elicit a categorical answer out of both Lopez and Goldstein, who confirmed they were not, in fact, an item. 

Lopez plunged into the publicity rounds for Office Romance after attending the high school graduation last Friday of one of her children, whose new trans identity the Daily Mail exclusively confirmed the day of the ceremony. 

The Jenny from the Block hitmaker and her third ex-husband, Marc Anthony, have 18-year-old twins who were initially christened Max and Emme Muniz.

Then, in June 2022, when the youngsters were 14, Lopez went viral after introducing Emme onstage as 'they,' indicating a nonbinary identification.

Last week, the Daily Mail viewed a public announcement showing that the teenager formerly known as Emme is now called Oskar Muniz and goes by 'he.'

Oskar, the twin who was awarded a diploma last Friday, was listed under the new name on a university program seen by the Daily Mail. 

Office Romance, which Goldstein co-wrote and which has a cast including Amy Sedaris, Betty Gilpin and Tony Hale, is out in theaters this Friday.
