But on Saturday, Kate Upton proved that despite being such a famous model, she certainly doesn't diet, as she chowed down on a meaty sandwich while watching the US Open.
The 21-year-old certainly appeared to be enjoying her food as she took a large bite of what appeared to be a meat-filled sub as she sat alongside fellow model Karolina Kurkova in the Moet & Chandon Suite.

And it wasn't only food that Kate indulged in, as she was also seen making the most of the flowing champagne at the event, which she drunk from a special VIP gold goblet.
While Kate has gone from unknown to world-famous model in a matter of months, she is certainly on the curvier side of the modelling industry.
But in a recent interview after a Vogue cover prompted 'fat' comments, Kate insisted she is happy with her body, saying: 'The things that they’re rejecting are things that I can’t change. I can’t change my bra size. They're natural! I can work out and I can stay healthy and motivated, but I can't change some things.

Ace!

donned sunglasses as she hit the court
And Kate certainly looked confident at the event, wearing a white dress with eyelet detail around the hem, which she teamed with strappy nude heels.
The star kept her long tresses pulled back from her face and wore minimal make-up, donning large black sunglasses as she took in the game.

Mother-of-one Karolina was equally fresh-faced and naturally stunning with her hair up in a ponytail and shades shielding her eyes, while she wore a fun long-sleeved black and white patterned dress.
The pair were present to watch as Serbian Novak Djokovic took on Stanislas Wawrinka of Switzerland at the USTA Billie Jean King National Tennis Center in Flushing Meadows.
Other stars to attend the match included Naomi Campbell, who took up residence in Djokovic's private box to watch the game.

Notoriously feisty Naomi went head-to-head with Karolina as rival coaches in realityTV modelling competition The Face earlier this year.
The stunning blonde suffered through numerous personal attacks from the 43-year-old as the pressure mounted on the show, so it's not surprising they chose not to sit together at the tennis.
Clearly into her sport, Naomi kept her eyes firmly on the ball as she sat with her hands clenched behind fellow Brit Sir Richard Branson.

The supermodel kept her long black hair down in loose curls and protected her skin from the hot sun with a navy Wimbledon cap and large brown sunglasses.
Just a day earlier, she was joined in the Moet & Chandon Suite by singer Maxwell as the pair watched Serena Williams earn her place in the finals after defeating Na Li.
Meanwhile, fellow avid fan Branson donned black shades and a dark grey T-shirt as he listened to the game's commentary through an earpiece.
Also taking in the action of Day 13 was a casually-clad Liev Schreiber, who enjoyed a chat with fellow actor Fisher Stevens without taking his eyes off the court.

The Good Wife's Julianna Margulies was barely recognisable as she protected her porcelain skin in a fedora and shades.
The 47-year-old went make-up-free and donned a simple black spaghetti-strap dress teamed with layered gold necklaces and bangles.
The star animatedly pointed out plays and conferred with a female friend as the game heated up.
