The bands, along with 5ive, 911, B*Witched and Honeyz, are co-headlining a tour of Britain after reforming for reality show The Big Reunion, which aired in the U.K. earlier this year (13).
The groups performed at Aberdeen's Aecc venue on Monday night (06May13) and they headed to Glasgow on Tuesday for their gig in the city - but the bus they were travelling in came to a halt near Dundee in the afternoon.
In a post on her Twitter.com page, Atomic Kitten star Liz MCClarnon writes, "The Big Reunion Tour bus has broken down. Anyone know of a taxi number near Dundee?!... Will the show still happen??"
Liberty X singer Michelle Heaton posted a picture showing several people sat on a grass verge next to the vehicle and added, "Oh oh! Big reunion is having a big breakdown! 10 taxis to Glasgow please!! Our beloved bus is going into early retirement.. we are stranded between Aberdeen & Glasgow."
