John Legend sings at his dogs' wedding

Singer John Legend sang at his dogs' wedding to promote a charity initiative.

The 36-year-old star serenaded his pet pooches Puddy and Pippa with his hit "All of me" at their nuptials on Wednesday. He even sprinkled rose petals down the aisle for the pets and even fed them their first piece of wedding cake on their big day, reports femalefirst.co.uk.

Legend's pets were appropriately dressed for the occasion in suit and bow tie and a bridal gown and they found time to take some photographs with their owner-turned-wedding singer in a photobooth at their marriage.

Legend wrote on micro-blogging website Twitter: "I'm so excited to play at your wedding, I filmed my rehearsal. My babies helped too! (sic)"

The singer even officiated the wedding for his and wife Chrissy Teigen's bulldog and French bulldog, who looked to be thoroughly enjoying their 'ceremony'.

Some fans thought the event might be an April Fool's joke but that was not the case as Legend in fact put on the dogs' big day to help promote a new initiative for his charity, The Show Me Campaign, which aims to give impoverished children an education.

Legend is encouraging fans to donate money to the initiative -- which is also raising money to rebuild the auditorium at the former South High School in Springfield, Ohio -- over the next 14 days, and anyone who does will be put into a prize draw to win a private performance from the star at an event of their choice.

The star has partnered with Omaze, which offers once-in-a-lifetime experiences which benefit charitable causes, to raise funds for the initiative.
