After giving a cheeky peak of her tattooed derrière as she ambled into the back of a taxi last week, Fearne Cotton ensured she kept everything firmly under wraps at an awards bash tonight.

The Radio 1 presenter stole the show at the Sony Radio Academy Awards, dressed in a flattering floor-length black and white printed maxi dress.

Fearne, 28, teamed her look by wearing her newly blondette hair in tumbling curls as she posed confidently on the red carpet.

Other stars of the industry who turned out included Capital FM presenter Lisa Snowdon, who took the plunge in a revealing LBD and The Saturdays singer Frankie Sandford, who wore a leggy, asymetrical white number.

There were also appearances from veteran news presenters, including Anna Ford and Selina Scott.

The pair showed they were growing old gracefully, with Ford, 66, dressed in a stunning turquoise Kimono set and matching jewellery and Scott, 58, opting for a long black kaftan-style top embellished with dark sequins that displayed her still-slender physique.

Endangered digital station BBC 6 Music was a double winner at the radio industry's biggest awards event.

U2 singer Bono is accustomed to winning prizes for his musical output but last night he was the unlikely recipient of a broadcasting award when his programme Elvis By Bono - in which he read his beat poet-style ode to the king of rock 'n' roll - was named Best Music Special.

It was one of many awards for Radio 4 at the event, which recognises broadcasting excellence and draws the key players from the world of radio.
