The 22-year-old rapper – real name Costas Dinos Contostavlos – admits he has had a crush on Laa-Laa, one of the popular children's television characters famous for their indecipherable language and TV stomachs.
When questioned about his crushes, he joked: "Laa-Laa from the Teletubbies. Because she's the yellow, female one. She's not Dipsy or whatever."
He also claims Laa-Laa is not the only children's character he would bed.
He added in an interview for Sony Ericsson's Pocket TV: "Sleeping Beauty would get it still."
His bandmate Tulisa – who is also his cousin – admits she has also had inappropriate fantasies in the past, specifically about Backstreet Boys singer Nick Carter.
When asked if she had any "naughty dreams" about pop stars, she replied: "Nick Carter. Something bad happened. We held hands and went on a lovely date."
Dappy recently revealed music saved him from a life of crime.
The 'Number One' star got mixed up with the wrong sort of people when he was a teenager and started to experiment with drugs and was involved in a gang.
He said: "If I weren't in N-Dubz I'd say I'd either be dead or in jail - one of the two if I never got involved with music.
"When I was a teenager I was getting up to all sorts to make money. Then I had a scare and realised I could go to prison for years."
