Jon Bon Jovi has always seemed like a stand up guy, and this weekend he proved it when he walked a fan down the aisle on her wedding day.

The 51-year-old singer surprised bride Branka Delic at her wedding to Gonzalo Cladera at the Graceland Wedding Chapel in Las Vegas, on Saturday.

Two months ago Delic had started an online petition, BonJoviWalkMeDownTheAisle.com, to have him at her nuptials which took place at the same chapel where he married his high school sweetheart, Dorothea Hurley, in April 1989. Somehow he got wind and just decided that he would do it, surprising her and pretty much making her wedding unforgettable. She said: 'I have memories for life which I'll never forget. Such an amazing man to take time from his schedule to come walk this crazy Aussie down the aisle... Jon..... I salute!'

Later, the musician took to his Twitter page to congratulate the happy couple, writing:

The singer - who played with his band Bon Jovi at the MGM Grand Garden Arena on the same night - also posted an image of him with Branka at the chapel on the social networking website.

And he even managed to throw a Bon Jovi pun in there. Hero.
