Dressed in a red fur bolero, Dame Shirley arrived at 8pm and entered her party flanked by the self-styled Fantasy Boys - a topless male dance troupe dressed in white satin trousers

While most of the 500 guests kept to the glitzy dress code, ageing punk rocker Siouxsie Sioux and designer Pam Hogg arrived in a low-cut metallic catsuits and garish make-up.

Despite celebrating her own birthday, Dame Shirley belted out 'Happy Birthday' to herself, before cutting her four-tiered red birthday cake.

Guests including Bruce Forsyth, Honor Blackman, Tony Hadley, Rolf Harris, Lord Brocket, Toyah Wilcox, Tony Christie and Raine Countess Spencer feasted on a lavish spread of Scottish lobster, langoustine, foie gras and Beluga caviar.

Andrew Davis, the von Essen chairman, paid £500,000 for the party.

Former Blind Date host Cilla attracted a lot of attention with her public displays of affection with her boyfriend John Madejski.

Cilla, who started dating the Reading FC boss in 2004, couldn't keep her eyes off her lover and was spotted caressing his hands at the dinner table.

Besides Dame Shirley's famous voice, upcoming singer/songwriter Tallulah Rendell and operatic boy band Blake provided the entertainment.

The diva was serenaded by Blake - who formed after meeting on social networking site Facebook earlier this year - before being kissed by all four members.

The Monaco-based singer spent months in a recording studio earlier this year making her hit remix album Get the Party Started, which was released in June.

The same month, she was helicoptered into Somerset to headline the Glastonbury Festival.

Dame Shirley wowed the festival crowd with hits including Big Spender and Goldfinger, dressed in a Julien McDonald dress and wearing £3,000 diamante-encrusted 'DSB' wellies.

And in July, she signed a new record deal with Universal Music Group's Decca Records, and is set to release a new album in the new year.
