Looking gorgeous in a head-to-toe black ensemble, Ariana cut a stylish figure for her day of promo in the capital.
Excited to see her British fans again, the 21-year-old couldn't help but stop and blow a kiss to those waiting near by - cute!
Outside the ITV Studios, Ariana made sure to show her fans some love before being whisked away to Radio 1 in her waiting car.
For her busy day of appearances, the 'Right There' singer looked nothing short of glamorous as she stepped out in black skinny jeans, a cute lace crop and an oh-so-gorgeous faux fur coat to cover up.
Now, that looks cosy!
Ariana teamed her outfit with a pair of patent platform heels and a small vintage handbag to match.
On the beauty front, the singer ditched her trademark high pony and styled her locks into a pretty half up, half down 'do.
Sporting a sleek burgundy manicure and flawless make-up on her face, Ariana finished her look with flicked eyeliner, a light coral shimmer on her lids and a darkened pink lippie on her lips.
Ariana's trip to London comes after she was spotted kissing rumoured boyfriend Big Sean while on a rollercoaster at Universal Studios.
After remaining quite coy about her romance in the past, surely puckering up with Big Sean is confirmation enough that they are now an item?!
Rapper Big Sean was previously engaged to Glee star Naya Riveria - the pair ended their engagement in April earlier this year.
Just three months after their split, Naya surprised fans by marrying new husband Ryan Dorsey following a whirlwind romance.
