We've already confirmed Tom Jones performing with Joss Stone and Beverley Knight teaming up with Dan Gillespie-Sells, so today we're delighted to be able to let you in on another Rockwell secret.

Ronan Keating whispered earlier about the prospect of the rest of Boyzone popping down to the gig, but as far as official collaborations go, his singing partner on the night will be talented Australian songstress Gabriella Cilmi.

Signed aged just 13, Gabriella is currently working on her 2nd album following the success of huge single 'Sweet About Me' in 2008. With a 16-year-career behind him, we're sure Ronan will be able to put his trademark growl to use alongside Gabriella's soulful vocals, perhaps on a version of 'Father and Son'. Gabriella has often spoken about the Cat Stevens original being the song that taught her 'music had the power to change lives' and with it being a famous hit for Ronan and Boyzone, we're pretty sure we might be hearing this on the night.

Let us know if you have any favourites you'd love to hear the pair sing and we'll be sure to pass them along.
