Tom Brady and Sofia Vergara Enjoying ‘Casual Fun Summer Fling’ — Much to Kim Kardashian’s Chagrin

Sofía Vergara’s hot-girl-summer hookups with Tom Brady are leaving Kim Kardashian feeling more insecure than ever after she was rejected repeatedly by the NFL stud.

Only a week after Kim “threw herself” at Tom at Jeff Bezos’ lavish wedding to Lauren Sánchez — only to be flatly rejected — sources say that the former quarterback, 47, made a beeline for the Modern Family star, 53, on a star-packed cruise aboard the Luminara superyacht in Ibiza, Spain, in early July.

“Tom was practically falling at Sydney Sweeney’s feet at the Bezos wedding and now he’s hooking up with Sofía, so it’s only normal that Kim would take it personally,” says a source.

Kim and Tom have met many times before, but he’s never expressed any interest in her, a insider says. “They’ve always had a good connection but as far as him pursuing her in any way, that has not happened. And it’s not like he doesn’t go after women when he’s into them.”

The lack of interest has been a big slap in the face for the billionaire SKIMS mogul, according to the insider. “Kim made it very clear to Tom that she was interested in him, and he’s always been super flirty, but nothing has ever come of it.”

So she took it hard when she heard that Tom had gone after Sofía in a big way, our source says.

“Kim hasn’t been having such a great summer. She’s worried that, at 44, she’s losing her superstar allure,” especially now that she’s been single for so long.

Meanwhile, Tom was definitely playing the field on his European vacation — after flirting with Sydney at the wedding, he quickly sidled up to Sofía, reportedly requesting to be seated next to the Colombian bombshell at dinner on the cruise, where an insider says he quickly had her swooning.

“Tom and Sofía are telling people it’s just a casual fun summer fling and won’t be anything more, so hopefully for Kim’s sake it will be over soon — because if they end up seriously dating it will be 10 times more humiliating,” says the insider.
