Kimberly: Pussycat Dolls were a strong unit
Kimberly Wyatt says the Pussycat Dolls were a "sisterhood" despite the reports of rivalries.
The 30-year-old star quit the girl group in February 2010 because she was unhappy with her position in the band but although it has been speculated that Kimberly did not have a good relationship with lead singer Nicole Scherzinger she insists the band were a strong unit.
