British boy band BBMak have gone down a storm in America -- but are still trying to make it big in their home country.The band's Christian Burns reckons his family, friends and fans in Britain do believe they've hit the big time the other side of the Atlantic -- but don't realise the extent of their fame.He says, "We try to describe to people in England and our friends and family the level of success we have had in America."And it's really impossible to do it just by saying, 'Oh yeah we went out for lunch and George Clooney was there and we hung out with him on the boat. The reply we get over here is, 'Yeah, right!'"I think they do believe we are massive in the States but everyone here takes it with a pinch of salt."BBMak also love mingling with the likes of the Backstreet Boys and Britney Spears in America but are less impressed by Christina Aguilera.Band member Ste McNally says the teen pop diva was having a bad day when they met her on a TV show and stormed off the stage when she was asked to sing her song again.He says, "They are all really nice people and seem to be great -- except for Christina Aguilera."We met her on a show. I don't know whether she was having a bad day but she was very unpleasant."We went on stage first and she came on afterwards. She was getting really annoyed because the producers on the show kept asking her to sing the song again. "People were waiting around in the audience and they were shouting 'BBmak!'. They were shouting this when Christina Aguilera was on stage and she just walked off." -- WENN
