Sienna Miller and Leonardo DiCaprio Secret Affair

NW magazine is reporting that Leonardo DiCaprio is set to go public with his new love Sienna Miller.
The actor reportedly dumped his girlfriend, model Bar Refaeli, for the blonde actress, who's finally ended her on-again/off-again relationship with Jude Law, 34.

Insiders say that Sienna, 25, has been dating Leo, 32, despite telling pals that she would only date men her own age.

"They got on really well, though Sienna was adamant she never wanted to date an older man again after being dealt a blow with Jude," says an insider. "But as they spent more time together their feelings for one another blossomed."

Sources say, Sienna is not so sure about Leo yet, she is rumored to be harbouring feelings for actor Daniel Craig, who she had a fling with several years ago when they co-starred in Layer Cake.

"There is real chemistry between them," says a pal.
