The pair, who began dating in August 2004 after Brook's split from THE TRANSPORTER star Jason Statham, will marry next year (06), but have yet to reveal the exact date.
Brook says, "We still haven't set a firm date but the ceremony is almost certainly going to be in Greece now.
"Billy's mum is Greek, he lived out there for four years and speaks the language fluently. I've never been to a Greek wedding but I've seen videos and they look amazing - so lively."
And British Brook is determined to embrace local culture: "We'll have a really traditional ceremony with both our families around us - hopefully in 2006.
"We're thinking of Scotland as a honeymoon destination."
