Singer says Russell Brand's ex 'didn't have a clue' about him

Kat fight ... Geri Halliwell and Katy Perry
GERI Halliwell has sharpened her claws over Russell Brand's ex wife Katy Perry saying she "didn't know what made him tick".
The 40-year-old Spice Girl, who is dating Russell, is thought to have said that his ex "couldn't handle" him.The ginger singer has been boasting about how well the odd couple are suited and how she's a better match with Rusty than his ex spouse.
Geri reckons she and new man Russell won't bomb as quickly as he did with Katy because she “didn't have a clue” about dating the comedian.
According to sources, the mother-of-one who called it a 'whirlwind romance' says Katy didn't have 'the patience or maturity to understand him'.
But rumours are rife that although Geri's smitten, Russell's cooling things down as he's not ready to settle again so soon after his divorce.
Geri took Russell househunting in Devon at the weekend and it's thought that put the nail in the coffin.
If their 13-day relationship has fizzled out it makes Katy and Russell's 14-month marriage look like an eternity.
