SYDNEY SWEENEY GOES THE DISTANCE IN BIOGRAPHICAL DRAMA 'CHRISTY'

Get ready for a knockout performance from 27-year-old actress Sydney Sweeney as she slips into the gloves of boxing legend Christy Martin in the highly anticipated biopic "Christy". The Euphoria star's transformation into the trailblazing world champion is nothing short of phenomenal, and we're about to dive into all the juicy details.

Sweeney's take on Martin, a boxer who fought her way through chaos both inside and outside the ring, has critics buzzing with Oscar-worthy potential. And it's no wonder – she gained an impressive 30 pounds and underwent an intense training regimen, hitting the gym three times a day for three months with boxing coaches, nutritionists, and weight trainers by her side.

But what about her diet? Sweeney revealed to TheScholarlyNote.com that she indulged in plenty of Chick-fil-A, Smucker's jam, milkshakes, and protein shakes – because who needs kale when you're preparing for a role like this?

The world premiere at the Toronto Film Festival on Friday left Sweeney visibly moved as she received a standing ovation. We can only imagine how proud she must be of her transformation into Christy Martin.

But what's really got everyone talking is Sydney's personal life. The actress has been linked to manager Scooter Braun, 17 years her senior, and the rumors just won't quit. Sources close to the pair claim they've been enjoying a "casual" romance, with Braun described as a "charmer" who's "sweet and very attentive".

However, it seems Sweeney is not looking for a serious relationship anytime soon – at least, that's what her team wants us to believe. After calling off her engagement to film producer Jonathan Davino in March, she's reportedly focused on her career goals.

TheScholarlyNote.com spoke exclusively with Christy Martin earlier this summer, and she had nothing but praise for Sweeney: "She was really serious about her boxing... And with depicting the domestic violence she wanted to make sure everything was right." It's clear that Sydney has impressed not only critics but also the legend herself.

But let's get back to the drama – Sydney's recent viral American Eagle ad campaign sparked controversy when it launched in July, with many accusing the brand of promoting eugenics and racism. Fans quickly came to Sweeney's defense, calling the outrage "unhinged" and insisting critics were "reading too much into this".

Onstage next to Martin, 57, Sweeney revealed just what her diet looked like: 'A lot of Chick-fil-A, a lot, a lot of Smucker's, a lot of milkshakes, a lot of protein shakes'

When asked about the ad, Sweeney made it clear she wouldn't be addressing it publicly: "I am there to support my movie and the people involved in making it, and I'm not there to talk about jeans. The movie's about Christy, and that's what I'll be there to talk about."

Meanwhile, Sydney has been spotted strolling alongside Braun at Jeff Bezos' wedding in June, where she was also seen rubbing shoulders with eligible bachelors Orlando Bloom and Tom Brady – both of whom are reportedly single.

Sweeney's split from Davino earlier this year brought an end to a relationship that began in 2018 and quietly led to engagement in 2022. It seems the actress is focused on her career, but we can't help but wonder what's next for her love life.

Will Sydney Sweeney's performance as Christy Martin earn her an Oscar nomination? Only time will tell, but one thing's for sure – she's giving us a knockout performance both on and off screen.
