The former model - who is currently embroiled in a bitter divorce battle with Beatrice's father Paul McCartney - hired actors dressed up as famous characters, including Snow White, Tinker Bell, and Cinderella, to entertain the tot and around 60 of her friends over the weekend.

A cinema, fountains, bouncy castles and trampolines were erected in the grounds of Heather's $6.5 million East Sussex home.

Beatles legend Paul also attended the party, but left after 20 minutes.

A source said: "Beatrice is Paul's world and there was no way he wasn't going to be there. But he doesn't get on with Heather's family."

Birthday girl Beatrice also received a pony as one of her presents.

In the evening, Heather - who recently rejected a $100 million divorce settlement from Paul - also threw a lavish black tie bash for over 100 guests, which ended with a stunning fireworks display.

The source added to Britain's The Sun newspaper: "It was one hell of a party and cost a fortune. To Heather that amount is small change."

"Some guests took home champagne and wine but it's peanuts to her. She just wants to be popular."
