Celebrity Beauty Trend Alert: Summer 2010's Red Lips

Cameron Diaz at the premiere of Knight and Day in Spain

It’s official: red lips make a sizzling summer look! Cameron Diaz showed off killer red lips with her asymmetric gunmetal grey Lanvin dress at the premiere of her new film, Knight And Day – the hotly tipped action comedy in which she stars alongside Tom Cruise.

And just in case you thought red lips were a rare summer sighting, Alexandra Burke and Karen Gillan were both sporting show-stopping pouts at the Sex And The City 2 premiere in London recently. These lovely ladies have not only proved red isn't just for autumn-winter, but that any skin tone or hair colour can pull off the ever-glamorous shade. We say get a red lippy in your summer make-up bag now! YA
