Katie's crush on gorgeous George hots up

Katie Holmes has reportedly enjoyed a string of dates with George Clooney.

The 34-year-old actress - whose recent romance with her 'Mania Days' co-star Luke Kirkby is said to have "fizzled out" - was a guest at the hunky actor's 'Gravity' premiere in New York earlier this month and came after the pair enjoyed several intimate dinners after bonding at a friend's recent dinner party.
