Mother-of-four Katie is well known for her love of horses, so no wonder she was beaming as she posed for photographs on day one of the famous event.
While we may have experienced unseasonably warm weather over the weekend, today was noticeably cooler so Katie wrapped up warm in a furry gilet over a coat with elaborately coloured sleeves.
The rest of her outfit, down to the boots, was white. Let's hope she stays away from the muddy racing field then!
Katie had told fans via Twitter how excited she was to be at Cheltenham and, on arriving, simply tweeted: "Wow, what a view."
The businesswoman, 35, has been a rider most of her life; viewers of her former reality shows will remember frequently seeing her out riding or down at the stables.
She even launched her own range of equestrian clothing, KP Equestrian, in 2008, and a line of kids' books called Katie Price's Perfect Ponies.
Well, she certainly brings a bit of glamour to the equestrian world, doesn't she?!
Katie has been keeping a relatively low profile away from the celebrity circuit over the past year - and what a year it's been! She married Kieran in the Bahamas in January 2013 following a whirlwind romance then gave birth to their first child together, Jett, that summer.
The model has largely kept Jett away from the cameras since his birth so we're not sure if he was along at Cheltenham for the day too. (Katie is also mum to sons Harvey, 11, Junior, eight, and daughter Princess, six, from previous relationships.)
Katie's visit to Cheltenham came after she confirmed she'd signed a new book deal with Random House to release a new autobiography and novels.
No doubt we'll be hearing lots more about life with Kieran and baby Jett, then!
