LEO DYING FOR YOUNG NEW LOOK

Fears losing fed-up galpal

- 

SPRUCED-UP Leonardo DiCaprio has been showing off a cleaner version of himself, and sources tattle it's the Tinseltown Don Juan's last-ditch effort to keep catwalk beauty Vittoria Ceretti from walking — after she blabbed that she refuses to be a trophy girlfriend.

Sources say the 50-year-old Wolf of Wall Street hunk and Hollywood's most notorious model-chaser is pulling out the stops and hiding his gray hairs in order to hang onto the spirited 26-year-old signorina.

“Vittoria made comments about how people don’t care about the other half of a couple and only care about the famous person, and how sick of it she was,” says an insider.
