The boy bander posted a cover vid on Twitter, writing: "For all you lovely Spanish fans! :) hope I did your language justice! Lemme know if I pronounce anything wrong!"
We detect a touch of shady shade in that tweet as old mate Connor insists that he wants to get the language right 'cos it would be offensive to mispronounce the lyrics.
The Vamps fans who obvs had taken offence to JB's poor Spanish singing in the past responded to Connor's diss in the comments.
Look out JB, you've got some competition!
