Ariana Grande loves embarrassing Ed Sheeran.
The 'Problem' singer admits she has an "inappropriate" sense of humour and finds her flame-haired pal gets easily flustered with her daring jokes.
She said: "I can be known to have quite an inappropriate sense of humour.
"And Ed Sheeran is so British and embarrasses easily. It's so easy to make him blush.
"People often think I'm totally censored, so I love to catch them off guard."
Ariana recently teamed up with ex-boyfriend Nathan Sykes on 'Over and Over Again' but insists it wasn't awkward getting into the recording studio with her former lover.
She said: "We're friends and I'm so happy with how the song turned out."
And now the 22-year-old beauty is hoping to collaborate with more British stars.
She told LOOK magazine: "I really love Adele, Jessie J is my girl - collaborating with her [n 'Bang Bang'] was super-cool. She brings such a different vibe. I was buzzing off her energy.
"Ed is obviously a legend.
"The Brits know how to do it - just more proper and washed down with a nice cup of tea."
