|Robin Maughan woked as a Frankie Valli tribute act in UK|
Robin Maughan, 34, was found guilty of secretly taking more than 100 indecent photographs and videos of underage boys and girls.
The pervert also encouraged children to send him indecent images of themselves, reported Mirror Online.
Maughan works as an entertainer in England, where he is known for his tribute act to Four Seasons lead singer Frankie Valli.
He pleaded guilty to 21 charges, including sexual abuse of an underage boy.
A man and a woman — who were 14 and 15 when he sexually abused them — wept in the public gallery as Maughan confessed to his crimes.
Leicester Crown Court heard how he made 17 videos of two boys, ages 10 and 12, in various stages of undress without their knowledge.
Judge Robert Brown told Maughan he will be sentenced on March 10.
