Aguilera encourages Spears to lose weight

Christina Aguilera decided to encourage new mother Britney Spears to lose weight when sending her a gift package.

The singer, who recently accused Britney of "letting herself go", sent the star presents including a corset and a diet handbook, to help her shift her three-stone weight gain, following the birth of son Sean Preston.

"I'm thrilled and overjoyed for her and wish her all the best," Christina told the Daily Star. "Hope she likes her gift."
