In April 2015, the pair had arranged a lunch meet at a Belgravia restaurant to try to clear the air between them following gossip about a friend's affair.
During the meeting, Ward shoved and threw a napkin at a "shocked" and "humiliated" Sinitta, Westminster Magistrates' Court heard.
Ward was warned by District Judge Elizabeth Roscoe that she would be bound over in the sum of £500 ($712 USD) for three months and ordered to keep the peace and be of good behaviour. No costs were awarded.
"I am going to deal with it quite unusually because I think this quite frankly is, to use an old-fashioned phrase, 'a storm in a teacup,'" said the judge. She added that the fact the court "has had to spend two days (hearing this case) and have a (police) officer here for two days is a nonsense."
After the ruling, Ward said: "I am disappointed the court has found a prod to Sinitta's shoulder to amount to the lowest form of common assault."
"I am however delighted that the court found me to be a truthful witness and rejected Sinitta's complaint that I punched her and tried to glass her."
She added: "They were disgraceful allegations which were untrue and the court did not accept her evidence."
