WATCH: Parrot NAILS Sia's hit Chandelier

Evidence that SIA can’t actually sing a note and is, in fact, hiding a parrot under her wig has emerged online.

Rumour has it the Cheap Thrills hitmaker hired a parot to belt out her chart bangers after the explosive video above was leaked online.

The footage has baffled music executives and the bird kingdom and called into question her claim to the FOUR Grammy nominations she’s just received.

Say what???

We think SIA’s sidekick – the talented little girl that dances in all her videos – knows she’s up to something!

Regardless, the unidentified bird really does give the Australian singer a run for her money!
