Justin Bieber has taunted Taylor Swift on Instagram.
The 22-year-old singer posted a picture of himself on a video call with Taylor's ex Calvin Harris and Kanye West, who she is embroiled in a public feud with, and captioned the image: "Taylor swift what up (sic)."
Taylor, 26, reportedly was not impressed with Justin's on/off relationship with her best pal Selena Gomez, 24, from 2011 to 2014 and it has been claimed that she urged Selena to dump him.
And Calvin, 32, would have had plenty to say after his bitter break-up with Taylor in May and her subsequent new relationship with Tom Hiddleston.
He also recently slammed his former lover in a lengthy Twitter rant after it emerged she had secretly written his song This Is What You Came For, blasting her and her team for "going out of their way to try and make me look bad at this stage."
He added: "I figure if you're happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do.
"I know you're off tour and you need someone new to try and bury like Katy [Perry] etc. but I'm not that guy, sorry. I won't allow it. Please focus on the positive aspects of your life because you've earned a great one. God bless everyone have a beautiful day."
Kanye has recently been involved in a huge public spat with Taylor over his controversial single Famous, after she claimed she didn't give him permission to sing about her.
However, his wife Kim Kardashian West decided to leak a series of videos on Snapchat which featured the rapper on the phone to Taylor discussing the controversial lyrics and she appeared to give it the go-ahead.
