Dale Winton's funeral was held in central London, on what would have been his 63rd birthday.
The television presenter was found dead at his home in Whetstone, North London on April 18, 2018, as reported by BBC.
A spokesman for Scotland Yard said that police were treating the death as unexplained but not suspicious.
Winton's memorial service took place at a church in central London on May 22, his birthday.
His close friends celebrated his life with a non-religious humanist funeral ceremony from Humanists UK.
The celebrity guests who were spotted at the funeral include David Walliams, Gloria Hunniford, Christopher Biggins, Piers Morgan, Martine McCutcheon, and Anthea Turner.
McCutcheon and Walliams gave readings at the funeral. Winton’s godsons, Josh, Ben, and Louis Linsey, also gave tribute.
Walliams has described Winton as "the best company, always outrageous and hilarious." He added that the star "adored being in show business and loved meeting fans."
In a 2016 interview with ITV's Loose Women, Winton revealed he battled a bout of depression.
He said: "Listen, there are worse things in the world - but I had depression and I didn't realize."
"I always thought, 'Get over yourself.' But my mum died of it. It exists and anybody out there who has had it knows it exists. I didn't want to put one foot in front of the other - but for a couple of really good friends," Winton added.
Winton, whose mother committed suicide in 1976 while suffering from depression, also said that his friend, Walliams, has always been his support system.
In 1986, Winton began his television career on Pet Watch. He shot to fame when he presented the show Dale's Supermarket Sweep from 1993 until 2001 and again when it was rebooted in 2007.
He also presented the National Lottery game show In It to Win It, Pets Win Prizes, and The Other Half.
