Singer Christina Aguilera reportedly turned down front row seats at a Britney Spears concert.

Aguilera, 28, was allegedly offered the chance to see Spears, 27, perform recently but did not take up the offer.

A source said: “Christina thinks that Britney is all style, no substance. She thinks the only reason that Britney came back is because people felt very sorry for her.”

Spears is currently in the middle of her world tour and has recently performed eight shows in the O2 Arena, London.
