Brooks Nader experienced an embarrassing wardrobe slip-up when she spilled out of her revealing top while celebrating in Las Vegas, amid recent rumors of her being part of a ‘love triangle’ with tennis stars Jannik Sinner and Carlos Alcaraz.

The model, 28, partied the night away during GRAND Reveal Weekend at Marquee Nightclub inside the Cosmopolitan of Las Vegas hotel on Saturday night.

She sizzled in a figure-hugging black jumpsuit, which had an extremely low-cut neckline, leaving her ample cleavage on full display.

She paired the look with some dark shades and nude pumps, and left her blonde locks in loose waves.

But the star had a slightly awkward moment at one point – while filming a video of herself dancing, she completely flashed her nipples at the camera.

The 28-year-old was joined by her sisters Mary Holland Nader, Sarah Jane Nader, and Grace Ann Nader, who looked equally as glamorous.

Mary Holland, 26, opted for a tiny white dress, while Sarah Jane, 22, wowed in a sparkling gold number.

Grace Ann, 25, for her part, wore a mini skirt and matching bra set, which she paired with a leather jacket and cowboy boots. 

The sisters set fire to Vegas nightlife, dancing and sipping cocktails until the wee hours of the morning. 

Even though reports indicated a sharp decline in Las Vegas tourism this summer, it didn’t seem to affect the festivities at Marquee on Saturday.

In addition to the celebrity appearances like Brooks and her sisters, roughly 4,000 people turned up to celebrate.

The vibe felt like a throwback to the 2000s club scene as Las Vegas saw only 4.56 million passengers in August, marking nearly a six percent drop compared to the previous year.

Brooks’ night out follows news swirling that the social media influencer was reportedly dating both Sinner and Alcaraz during the US Open period.

Speculation arose when her sister Grace Ann hinted that Brooks might be romantically linked to Sinner, playfully noting that the person was ‘someone whose name rhymes with winner’ in August.

However, Brooks denied the rumors on Jimmy Kimmel’s popular late-night show, implying she was actually seeing another tennis professional instead.

Soon after, Grace Ann claimed at an event that Brooks was dating Alcaraz, stating that the ‘rumors were true’ and he was ‘the man of the hour.’

In a turn of events reminiscent of the movie Challengers, reports emerged soon after that Nader was dating both Alcaraz and Sinner at the same time – who were set to face off in the men’s US Open finals.

However, journalist Alberto Guzman – citing information from Alcaraz’s inner circle – said on Spanish TV show No Somos Nadie that Brooks was not dating the Spanish star.

‘They’re not dating, it’s not an official relationship,’ he said. ‘[Alcaraz] confirmed to those close to him that he is single and has no intention of having any serious relationships. Perhaps she is not well informed.’

Even so, Brooks added to the speculation with comments she made on late-night television show Watch What Happens Live weeks later.

When asked about the Challengers-esque dating set-up by host Andy Cohen, Brooks seemed deliberately vague. 

‘I would just say, a lady never kisses and tells – especially twice, that’s just not nice,’ she said.

‘Dating is such a loose term these days. It’s just… I don’t know. By the way, my only thing is, guys do it all the time, so why can’t I do it?’
