Twitter erupted with loads of hate from viewers with people labelling her a "fraud" for not singing live, calling it a "bad performance".
Now, an insider has confirmed to TMZ that she was, indeed, singing to a backing track during the chorus like performers including Christina Aguilera, Nick Jonas and Hailee Steinfeld did on the night, but the singing was all her during the verses.
This is a common practice during live performances, particularly at award shows.
So in summary: could everyone back off queen Sel pls?
