Colourful singer Mika is offering an incredible prize to fans who donate money to a charity that saved his sister's life back in 2010. 

The 'Grace Kelly' star's sibling, Paloma Penniman, was rescued by London's Air Ambulance service after falling from a window at her home and becoming impaled on a metal railing and Mika has now decided to give something back for the organisation's admirable work. 

Writing on his official website, Mika explained his intentions and the contest he is about to launch:

"To celebrate the 5th Birthday of the MFC and to raise funds for the very worthy London's Air Ambulance, Mika is offering one lucky winner a pair of tickets to any Mika Show in the whole world!"

"The prize includes flights from your home country and accommodation for 2 people. For each £10 donation you will receive a raffle ticket by email. Please include your MFC username when making your donation and check the box to agree to share your details."

He also took to Twitter last night and added, "London you could claim a trip 2 Sydney if you so chose. All in aid of raising money for London's air ambulance with MFC."
