Heather Mills splashed out a reported £100,000 (US $200 thousand) on a Disney-themed fourth birthday party for daughter Beatrice.The former model - who is currently embroiled in a bitter divorce battle with Beatrice's father Sir 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 £3.2 million (US $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 £50 million (US $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."
