Diaz, DiCaprio 'get cosy' in London

Cameron Diaz and Leonardo DiCaprio are rumoured to be romantically involved after being spotted in London together.

According to The Mirror, the pair attended London club Maddox and shared dinner at Shoreditch House on Saturday.

The Hollywood stars are both reportedly single, with DiCaprio rumoured to have split from model Bar Rafaeli earlier this year. Diaz recently ended a year-long romance with British model Paul Sculfor.

"They were laughing a lot and very touchy-feely and they ignored everyone else," said a source. "They seemed very close and comfortable with each other's company. Leo was pouring her glasses of champagne."

The duo allegedly returned to DiCaprio's Knightsbridge apartment at 3am.
