Wilde Monroe

Some like it hot – but curvy Kim Wilde knocked ’em cold yesterday as a Marilyn Monroe lookalike. The singer slipped sexily into Billy Joel’s 45th birthday bash showing off her trim figure in a clinging number.

But a sad Billy, who recently split from wife Christie Brinkley, told a star-studded party as he cut his cake: “I’d better get used to this. I’m going to have to slice a lot of me up.”
