Sheen absent for sons' birthday bash

Charlie Sheen wasn’t invited to his twin sons’ second birthday party yesterday.

The former ‘Two and a Half Men’ actor’s estranged wife Brooke Mueller held a lavish bash for Bob and Max – who turn two today – at Paris Hilton’s family home in Bel Air, California, and while guests included Nicky Hilton and boyfriend David Katzenberg and reality TV star Adrienne Maloof, the boys’ dad was noticeably absent.
