Kimberly Wyatt says Christina Aguilera has earned the right to be a diva - because she is so talented.
The 43-year-old singer-and-dancer "spent a lot of the time" with the 'Genie in a Bottle' hitmaker when Kimberly's girl group the Pussycat Dolls opened her 'Back to Basics' tour in 2007, and the 'Don't Cha' singer was in awe of her vocals and although Christina "might be a bit of a diva" she has the talent to back up the attitude.
