Britney Spears has gained an unlikely ally in the lip-synching scandal brewing Down Under. Outspoken rocker John Mayer has jumped to the defense of the pop star, who has been criticized for “performing” pre-recorded numbers during recent concerts in Australia.

Disgruntled audience members slammed the 27-year-old in Australia’s Daily Telegraph Friday for her pre-recorded Circus Tour. “It was a waste of $200 — I could have got four pairs of shoes for that,” one concertgoer complained. For his part, John just can’t understand what all the hoopla is about.

“If you’re shocked that Britney was lip-syncing at her concert and want your money back, life may continue to be hard for you,” Mayer posted on his Twitter account Sunday night.
