Rihanna is on the waiting list for one of next year's expensive space flights. She joins a list that includes Justin Bieber, Paris Hilton and Brad Pitt.

Rihanna will spend $1 million for three seats on Richard Branson's Virgin Galactic. She hopes to take her brother Rorrey and a bodyguard along.

A source said: "Rihanna has already put down a deposit for the flight. She has been obsessed with space since she was a child so it would be a dream come true for her."
