Ariana Grande and Pete Davidson have made their romance Instagram official.

The 'No Tears Left To Cry' hitmaker and the 24-year-old actor have been rumoured to be dating since last week, and the pair have now taken to social media to seemingly confirm their romance after Pete posted a picture of the new couple dressed in matching 'Harry Potter' robes.

Ariana's new romance comes just weeks after she ended her two-year relationship with rapper Mac Miller, before dubbing their time together as "toxic".
