Big Sean has rubbished reports that he threatened Justin Bieber on Twitter after the singer got a little too close to his girlfriend Ariana Grande on stage!

As we previously reported, the Biebs couldn’t keep his hands off Ari as he joined her on stage in Los Angeles this week, with the pair putting on a raunchy performance of her tune 'Love Me Harder'.

[related]Shortly after footage of their duet emerged online, Sean took to Twitter to simply write the word “Wow”, which he quickly deleted.

However, another tweet was later posted on his timeline, which read: “This kid is about to learn not to touch my girl like that. Beliebe that.”

The message was retweeted over 5,000 times, with it seeming that the 'Dark Sky Paradise 'rapper had issued a stern warning to his pal and 'As Long As You Love Me' collaborator.

However, a rep for Sean has since told TMZ that the tweet was totally fake, adding that he and Justin are “good friends” and that “he and Ariana are just fine”.

They also cleared up speculation that another tweet, which read “so many times in my life I wish I could of been at 2 places at once”, was also not aimed at JB, but was actually about how much he misses his friends and family while on the road.

Phew, we’re not sure we could handle another celeb feud!
