The new host of the ITV2 show was spotted outside the BBC Radio 1 studios in London earlier today (15 July) - on her birthday!
Such a special day calls for a gorgeous outfit, and Sarah-Jane's ensemble certainly didn't disappoint...
The starlet looked effortlessly cool in a colour block pink and coral top which she teamed with mega-tight skinnies, rolled up at the ankles.
She added a hefty dose of glamour to her relaxed ensemble with pointed black heels - which were a high street buy, costing £65 from Office - while toting a matching bag over one shoulder.
Sarah-Jane also flaunted a totally immaculate white manicure while holding her iPhone and sunnies in one hand, completing her ensemble with a dainty chain necklace.
Her hair was styled in a middle parting with the lengths tonged into bouncy, voluminous curls, and she showcased flawless skin and mega-fluttery lashes, plus her trademark bright red pout, of course!
Just last month it was announced that Sarah-Jane would be replacing Caroline Flack as the new co-presenter of The X Factor's spinoff show, The Xtra Factor.
And it was just a matter of days before Sarah-Jane stepped out for her first day of work, looking totally amazing in a white shirt and leather skirt.
We can't wait to see what other fab wardrobe choices she has up her sleeve!
