Sienna Miller & Leonardo DiCaprio 'just friends'

At the Golden Globes, actress Sienna Miller dismissed press reports romantically linking her to actor Leonardo DiCaprio.

She told red carpet host Ryan Seacrest there was "absolutely no truth in it".

"I haven't seen him in a year and half, we've just been catching up, we're buddies, old friends."

On Sunday NW Magazine, reported that Leonardo DiCaprio was 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."

"It's lovely to be here and see people you know but the whole process is genuinely quite scary
