Ciara wore her long human hair wig parted down the middle and flowing down her back accentuating her newly acquired BBL. Rumor has it that Russell approved Ciara's BBL before she went under the knife.

The annual Serpentine Summer Party, hosted by publishing magnate Michael Bloomberg, is one of the hottest tickets on London's summer social calendar.
