Found this on Antony Costa's twitter (formerly of Blue), the band's got his little brother in it, far left and what looks like Jay. Thought you'd all be interested Apparently they've started to doing small appearences but, nothing big as of yet.
Antony has them listed from left to right as: Louis, Chris, Mark, Jonny, Jay.
This is Jays 3rd including S-Club Juniors how ever to say they wont get any where is slightly unfair. What you may not know is Mantrixx are managed by te same lady which brought New Kids on The Block and B*witched to fame, she also helped make Whitney Houston a big name.
Mantrixx are produced by one of the most highly regarded producers in the UK, known for top remixes on Girls Aloud, Lonie Gordon and many more not forgetting many Hits from Kylie Minogue, Sonia, Sinitta and Bros (to name but only a few).
The rumour is that Mantrixx will be supporting Blue on their come back!
