Alford of Holloway, north London, stood trial at St Albans Crown Court under his real name in September last year.
A jury was told the star bought a bottle of vodka for the two teenage girls which they drank at a friend’s house in Hoddesdon, Hertfordshire, in April 2022.
He was found guilty on four counts of sexual activity with the younger girl, and of sexual assault and assault by penetration on the older teenager.
He was jailed two months ago on 14 January as Recorder Caroline Overton said the offences had a “significant and ongoing impact” on his victims’ lives.
