‘summer fling.’

The two are ‘having fun’ but are not a couple, according to the insider. The source added that the notion of it being a romance is ‘ridiculous.’

The pair are both single following Sofia’s divorce from Joe Manganiello in 2024, and Tom’s split from supermodel ex Gisele in 2022.

Sofia and the former New England Patriots quarterback enjoyed a star-studded trip on the Luminara superyacht, and were joined by A-list guests including Naomi Campbell, Kendall Jenner, Kate Hudson, Martha Stewart, and Colman Domingo.

Irina Shayk, who was previously linked to Brady, was also aboard according to the source.

Setting sail from Rome, the two-night luxury cruise included drone shows and performances from Ellie Goulding, Sting, and Janelle Monáe.

Vergara even shared a photo of her and Brady seated together at a dinner. She stunned in a plunging black gown, while Tom flashed a big smile and looked handsome in an all-black outfit.

In the snap, J Balvin was pictured greeting her by giving her a kiss on the forehead.

Another photo from the trip showed Sofia with Ricky Martin on the 790-foot superyacht, which hosted 450 VIPs.

Following the voyage, the two have reportedly been spending time together in Ibiza.

The Luminara comes replete with 226 suites to accommodate a maximum of 452 guests. There are also five restaurants, seven bars, a wine vault, two swimming pools and a spa.

More than 700 art pieces decorate the ship, including works by Andy Warhol and David Hockney — and, in those five restaurants, there are menus from two James Beard Award-winning chefs, Fabio Trabocchi and Michael Mina.

Cruise tickets start at $11,900 for seven nights — while guests in the most lavish suites can expect to cough up as much as $78,000.

Vergara has been keeping fans updated and sharing sexy summer posts including photos of her rocking a bright Walmart bikini and videos of her dancing to Calvin Harris’s music.

On Wednesday she showed off her booty in a new image shared to her Insta Stories. The star was modeling a multi-colored one-piece swimsuit while enjoying her vacation in Ibiza.

Last month Sofia gave an insight into what she’s looking for in her next relationship, saying she wants her next boyfriend to be as rich as she is.

She admitted that she needs ‘fun in [her] life’ – but she isn’t interested in dating someone who isn’t financially independent.

Asked what she is looking for in her next relationship, Sofia said on the Today show: ‘I want to say the basic stuff, like health and somebody that loves me. And somebody tall, handsome.’

Brady also recently sparked romance rumors with Sydney Sweeney, 27, with reports claiming the pair danced together during Jeff Bezos and Lauren Sanchez’s wedding festivities in Venice; Both pictured arriving to the ceremony on June 27

‘I want somebody that has as much money as me or more, because if not, it’s a nightmare. They end up resenting you.’

The Hollywood star – who was married to actor Joe between 2015 and 2024 – shared: ‘I’ve been single now for a year and a half, and I kind of panicked once I got divorced. I was like, “I’m 52, what’s gonna happen? Where am I going to find [someone]?”‘

Despite this, Sofia is still in no rush to find love. She said: ‘I’m not really in a hurry anymore.’

Last year, Sofia claimed that she can’t be too ‘picky’ about who she dates.

The brunette beauty finalized her split from Joe in 2024, but she remains open to the idea of dating another celebrity.

Sofia told People: ‘I mean, it’s already hard for a 50-something-year-old woman to find someone. I’m not going to be now picky about, “Oh, he can only be a doctor. Oh, he can only be an astronaut.” No, I mean, I’m not that picky.’

Meanwhile Brady recently sparked rumors of a possible romance with Hollywood star Sydney Sweeney, with reports claiming the pair danced together during Jeff Bezos and Lauren Sanchez’s wedding festivities in Venice.

TMZ also claimed that he was ‘chatting up’ Sweeney at the hotel bar.

Brady also enjoyed a day out with actors Orlando Bloom and Leonard DiCaprio in Venice, with the three seen sipping on cocktails poolside.

Brady and Bloom were also pictured wandering the streets of Venice alongside Sweeney, with the White Lotus star described as the ‘most sought after person’ at the party.

‘Everyone wants to talk to her and every guy that has been in her presence has talked about how stunning she is in real life,’ a source said.

She and Brady sent social media into meltdown after reports suggested they struck up a possible romance.

But a source claimed the former quarterback ‘danced with everyone’ at the wedding – not just Sweeney but also model Brooks Nader, to whom he was briefly linked last year.

Brady got an invite to the wedding because the former quarterback and Amazon billionaire Bezos are believed to have grown close over the past few years, having become neighbors at Indian Creek in Miami.

Brady has been linked to several high-profile women since his split from Gisele, including Sydney, Irina, and Brooks.

The athlete has three children: 15-year-old Benjamin and 12-year-old Vivian with ex-wife Gisele, and 17-year-old Jack with actress Bridget Moynahan.

Meanwhile following her divorce from Joe, Sofia — who shares son Manolo, 33, with ex Joe Gonzalez — has been linked to orthopedic surgeon Justin Saliman.
