Lauren Bennett, the blonde bombshell that sang on LMFAO's No. 1 hit "Party Rock Anthem,"  was confirmed as the first member of the new Pussycat Dolls.  The group's creator Robin Antin said earlier this month that he was recasting the group for another album and tour, and Bennett, who was also previously in the ill-fated girl group Paradiso Girls, is the first member.
