Amanda Holden, 46, displays remarkably youthful visage

Revealing outfits have become something of a TV trademark for the Britain’s Got Talent host.

But Amanda Holden was at the mercy of the wind on Wednesday night as she flashed more of her leans legs than she’d anticipated, in a mad dash from London’s Apollo Theatre.

Looking remarkably youthful, the 46-year-old stepped out in a thigh-skimming blazer-style dress for the West End launch of Everybody’s Talking About Jamie.

Amanda’s dress threatened to overexpose her lean legs as she left the theatre, when one side kicked up in the wind.

For all its allure and sparkle, the dress didn’t detract from Amanda’s gorgeous beauty look, which drew attention to her remarkably smooth and wrinkle-free visage.
