"People pay a lot of money to have collagen put in their lips," chuckles songstress Tina Arena. "so i'm lucky in that department, huh?" That perfect pout is hard to ignore, and that chestnut hair and chocolate-brown eyes complete the package of poppet turned sophisticate. In between writing for her next alburn, Arena, 32, is preparing to play the gypsy Esmeralda ("such a beautiful role") in the Notre Dame de Paris, a new musical opening in London's West End next month. Seperated from husband Ralph Carr, the former Young Talent Timer is seeing French sound engineer Jeremy Mathot and has become attached to her "glamorous" European base: " My life's been enriched a helluva lot by having had the experience of living in Paris and immersing myself in French culture." Time out means preparing meals for friends or grooving at a local nightclub. "I think, honestly, the best way to look great is to stay happy."
