Lauren - mother of Simon's son Eric - led the way in the glamour stakes at the black tie event

Millions may have been tuning in to see the latest twists and turns on The X Factor, but Lauren Silverman was putting on her own show as she stepped out on Saturday night.

Usually happy to let her superstar partner Simon Cowell grab the limelight, the 36-year-old was the one who made a dazzling appearance at the Shooting Star Chase charity ball at London's Dorchester Hotel.

Lauren - mother of Simon's son Eric - led the way in the glamour stakes at the black tie event, where a host of stars had gathered to help raise funds for the children's hospice.

She looked stunning in a floor-length burgundy fishtail prom dresses uk, complimented perfectly by simple jewellery and her hair neatly pinned back.

Meanwhile, the X Factor honcho stayed true to form and sported his go-to uniform of unbuttoned white shirt and tailored trousers.

Other guests who gathered at the event included Simon's close confidante Sinitta, who wore a sheer embellished blue prom dresses 2014, and former Celebrity Big Brother star Luisa Zissman, who wowed in black gown with a plunging neckline and a thigh-high split.

TV presenter Chris Tarrant was also among the glitzy revellers.

Hollywood legend Joan Collins ensured she returned to the UK to attend the event due to her role as a patron for the hospice, which helps over 600 families with terminally-ill children.
