Sadie FrostWe like to think there are no showbiz flies on us.

We pride ourselves on knowing our glitzy shizzle.

But Sadie Frost has thrown down the gauntlet...

She's claimed she's had a secret boyfriend for the last two years.

Sadie told Eve mag that she purposely keeps her romance on the down-low and out of the papers.

But this has confused us somewhat.

We've seen her spending oodles of time with muso Kristian Marr over the last coKristian Marr and Sadie in May 2008uple of years and they defo look more than friends to us. 

And as for purposefully shunning the snappers, take exhibit A for example (right).

They've been proudly kissing and no mistake.

So what's Sadie on about?

Is there another boyfriend, one she's slipped under our noses?

It's a mystery and no mistake but we do like a challenge.
