Fans will see the radio star make his dazzling debut in the rink on Sunday, despite having dropped his professional partner Angela just hours before they were due to perform.
The 27-year-old is best known as a presenter on Capital FM, waking up the nation on weekday mornings with Roman Kemp on Capital Breakfast.
While Sonny prefers to keep his private life out of the spotlight, Daily Star has done a deep dive into everything you need to know, from his relationship to his rise to fame.
While Sonny is a familiar voice on the airwaves today, back in 2012, he was a fresh-faced 19-year-old, trying his luck on Britain’s Got Talent.
Appearing before judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams, the Londoner performed as a member of the boyband Loveable Rogues.
Sonny played the ukulele for the group, performing alongside singer Te Qhairo Eugene and guitarist Eddie Brett.
The band made it to the finals of the sixth series but were beaten by performing dog Pudsey with his owner Ashleigh.
While he didn’t get to perform before the Queen in Royal Albert Hall, the BGT stint cemented Sonny’s status in the showbiz world, launching his career.
Last August, Sonny warmed fans' hearts when he announced he had got on bended knee before his longterm girlfriend Lauren Faith.
Six days into their sun-soaked jaunt to the island of Mykonos, Sonny proposed to the producer and songwriter during a boat trip around the Mediterranean.
Sharing images of the romantic moment, Sonny wrote: "SHE SAID YES. Couldn’t be happier to spend the rest of my life with the most beautiful soul I know. I love you so much xx.”
Lauren was just as thrilled, telling fans: “One of the most romantic days. When your best friend asks you to marry them.”
The pair had celebrated their three year anniversary in April 2020, with Sonny shedding a little light on the early days of their relationship.
Flame-haired beauty Lauren said “yes” to becoming Sonny’s girlfriend when he turned up to her house with flowers, “asking you to be mine”.
Marking the occasion, he said: "Thank you for being the best support I could ever ask for! Happy Anniversary – I Love You."
Having fronted Capital Breakfast since 2017, Sonny is best mates with his co-star Roman Kemp, who was a finalist on the 2019 series of I’m A Celeb.
The pair even holidayed together last summer, travelling to Greece as a gang and sharing behind-the-scenes pics from the jaunt over social media.
Since Sonny’s debut on Dancing On Ice, Roman has been showing his support, tweeting last week: “If you ain’t #TeamSonny we ain’t friends…”
Sonny is also good pals with fellow radio star Vick Hope, with Sian Welby recently taking her place in the recording studio.
Before Sonny joined Capital FM, he spent two years as a presenter on Phoenix FM, a community radio station serving the areas of Brentwood and Billericay.
Dancing On Ice airs on Sundays at 6pm on ITV.
