While Zayn throws some shade on Twitter...
Fans are still buzzing from yesterday's 1989 show where that other girl band, Fifth Harmony, joined Swift on stage to perform Worth It.
The Little Mix girls might find their parade slightly rained on when they get home, though, because just as they were introduced onto the sold out stadium stage, the former Almost Mr Perrie offered some of his own shade on Twitter:
Taylor was joined later on stage by actress Julia Roberts.
It was an eventful night for UK girl band Little Mix.Their recent attempt at a US takeover has been in full swing the past few weeks, with the girls performing everywhere imaginable and making sure to shade Perrie's former fiance Zayn Malik whenever and wherever possible. Tonight, Perrie, Jesy, Leigh-Ann and Jade were the 1989 Tour guests performing their song Black Magic with T.Swizzle.
