The Bangor-born beauty performed some of her hits at the party, which raised funds for a new heart and lung centre for London children's hospital Great Ormand Street as well as celebrating the launch of this weekend's British Grand Prix.
There to support their dad were Bernie's daughters Petra, 21, and 24-year-old Tamara, who were accompanied by their mother Slavica. The former Armani model and the racing mogul were granted a divorce in March after 25 years of marriage.
According to 78-year-old Bernie it was an "amicable split", and judging by Slavica's move of attending her ex-husband's party, they remain on good terms.
The bash was also a family affair for Stevenage-born driver Lewis, who brought along his father Anthony and brother Nick. Famous faces at the event included The Forsyte Saga actor Damian Lewis – enjoying a night out with his actress wife Helen McCrory.
