Katy Perry was at it again as she locked lips with the girls during a gig after party last night – enough already we know you want to get publicity for you album…. but.. Katy, whose hit single I kissed A Girl has toped the charts in 20 countries, was seen kissing the lead singer from AlphabeatRuby Lounge. Wearing a tight fitting blue dress, and printed tights, Perry danced and partied the night away.
