On Tuesday, Gaga and Ariana were among the stars who gathered at the Nokia Theatre to pay tribute to music legend Stevie Wonder.
And while they were honoured to be in the presence of 'Superstitious' hitmaker Stevie, it seems like the popstars were just as excited to finally meet one another too.
Following the taping of Stevie Wonder: Songs In The Key Of Life - An All-Star Grammy Salute, 'Problem' singer Ariana said she was "still on cloud nine" after enjoying a "girl talk" with Gaga, and meeting other music legends.
'Bad Romance' singer Gaga returned the compliment, saying last night (11 February): "@ArianaGrande you are a lovely sweetheart and I enjoyed meeting you so much!"
Ariana replied: "@ladygaga you are actually an angel. I loved meeting you too!! And Tony too! The cutest in the world."
Do we spy a potential collaboration on the cards?!
After the show, the pair cosied up for a photo backstage and they both looked very glamorous. While 21-year-old Ariana wore a printed navy jumpsuit, 28-year-old Gaga looked stunning in a sparkly silver mini dress.
