IT'S the tallest, fastest, steepest rollercoaster in the world and this summer it celebrates a bumper birthday.

The Pepsi Max Big One is five years old and Blackpool Pleasure Beach is holding a party to remember for the megacoaster on Monday.

On the guest list are all the celebrities who have ridden the Big One since it opened in 1994.

Invited to take a trip on the 235ft high 85mph ride are stars such as Zoe Ball, Robbie Williams, 911, Melinda Messenger (pictured), Tim Vincent, Boyzone and Shane Ritchie to name just a star-studded few.

And if you share your birthday with the £12 million ride you could join them absolutely free. Just take your birth certificate or similar proof showing you were born on July 5 to the Pepsi Max Big One where you will receive a special edition boarding card (height restrictions still apply).

A spokesman for the Pleasure Beach said: "It's been an amazing and incredibly quick five years. A lot of people can't believe it's the ride's fifth birthday already.

"It has been a huge success since it opened in 1994. We wanted to build a world beating ride and we succeeded.

"Everyone is really looking forward to Monday. It's going to be a great day."
