A gunman wearing a balaclava burst into a wedding reception and shot the groom, a court has heard.
Joshua Mitchell, 20, of Slough, was shot in the thigh in an apparent attempt to "sexually mutilate" him at Skyways Hotel, in Slough, Berkshire.
Jason McInerney, 20, of Romford, Kirk McInerney, 18, of no fixed address, and Martin Carty, 18, of north west London, deny Mr Mitchell's attempted murder.
They also deny an alternative charge of grievous bodily harm, and robbery.
Mr Mitchell told the court how his attacker had looked at the area he intended to target before shooting him. He was hit in the upper thigh.
His wife, Mary-Ellen Mitchell, 21, said her groom then tapped her on the shoulder and said: "I think I'm going to die."
Joshua Mitchell was due to marry Mrs Mitchell in August 2006, but they broke up after a row over a "trivial matter".
Reading Crown Court heard that during their break-up, Mary-Ellen Mitchell, then Miss Murphy, started speaking with Jason McInerney, who she said she knew as Paddy Delaney.
She told the court that she had met Mr McInerney, who she claimed shot her husband, several times while out with her aunt and sister.
He began showering her with expensive gifts and asked her out but she told him she still loved her estranged fiancÚ.
Mrs Mitchell told the court she stopped calling Mr McInerney and asked him not to call her after she and Mr Mitchell were reunited.
The trial continues.
