ROCKER Bono turned ordinary wedding singer for the day at a plush wedding reception in the US.
It was a Beautiful Day for billionaire Warren Buffett's granddaughter as Bono serenaded her guests at her nuptials.
The U2 lead singer stepped up to perform with the band at the extravagant wedding of Emily Greenberg in Omaha, US.
Bono performed 'Stand By Me' - the song popularised by Ben E King in the 1960s.
The rocker - who attended bandmate Adam Clayton's surprise wedding last week - gladly accompanied the band on stage.
About 285 guests attended the wedding of Emily and Tom Threlkeld and reception at Lauritzen Gardens.
The guests included Emily's grandfather, investor Warren Buffett who is estimated to be worth around €40bn, and her uncles Howard and Peter Buffett.
Bono's exclusive appearance was leaked on social networking site Instagram, where someone published a video with the caption: “Just your normal Omaha wedding.”
Bono was later photographed at a fashion show with wife Ali and their eldest daughter Jordan (24) during Mercedes-Benz Fashion Week.
The family were there to support Ali's clothing line Edun which was showing at the Skylight Modern yesterday.
Meanwhile it was revealed that U2's Adam Clayton and his new bride Mariana Teizeira de Carvalho are due to make their home in London where she owns a house in Westminster.
The couple tied the knot in a registry office in Dublin's city centre last week but are planning a second ceremony in the south of France.
Adam (53) will retain his property in Rathfarnham where family and friends held a small celebration after their nuptials.
He also owns homes in New York and France.
Mariana (35) works as an associate director of the prestigious Hauser & Wirth art gallery and the duo are planning a life in the UK capital.
Clayton was previously engaged on two occasions - to supermodel Naomi Campbell and Suzie Smith, a pretty blonde music PA who worked for Adam's manager Paul McGuinness's Principle Management company.
