Outspoken British singer Lily Allen has been snubbed by the equally outspoken Joan Collins.

On Thursday, the “Not Fair” hitmaker met the former “Dynasty” star for the first time at a party celebrating the 100th anniversary of London’s Selfridges Store. The pair were introduced and just as Lily leaned in to give the legendary actress a peck on the cheek, disaster ensued.

Joan quickly moved away, informing Lily that she does not exchange kisses with strangers.

(That’s polite people speak for: “Chick, I don’t know where your lips have been!” We hear you, Joan. You’ve really got to keep your guard up with this swine flu going around.)

Lily later discussed the puzzling encounter with Joan on her Twitter page, writing: “I was just introduced to Joan Collins, shook her hand and went to kiss her on the cheek. ‘I don’t kiss people I don’t know.’ AMAZING!”
