The video has already bypassed the one million mark and his has surprised The Vamps, who tweeted today (June 11):

"Woke up to over a million views on the Somebody To You video! That's crazy! Pls keep sharing."

The single meanwhile is due to be released in the UK on July 6.

The tune's original version, which did not include Lovato, features on The Vamps' 2014 debut album 'Meet The Vamps'.
