A-listers join birthday girl’s swanky bash

serious A-list star power. Orlando Bloom and Kate Perry, 42 and 34, arrived on a motorbike, while actress Reese Witherspoon, 42, took a tumble down the stairs as she left the bash.

Jennifer, who played Rachel Green in Friends and is said to be worth £185million, was dressed in a plunging black jumpsuit.

Barbra Streisand, 76, also brought a touch of old school class to the night.

She has been pals with Jen since 2010, when the actress paid homage to her by recreating her classic looks for Harper’s Bazaar.

TV host Ellen Degeneres, 61, was more casual in tracksuit bottoms.

The hotel was decorated with white flowers and candles as guests drank cocktails by the pool listening to the DJ.
