The girlband formed on the 'Popstars: The Rivals' TV show, failed to knock Mickey Harte from No 1 on the Irish singles chart this weekend, taking second place instead.
Girls Aloud's second single, 'No Good Advice', debuted at two on the chart, while Ireland's Eurovision representative Harte held on to the top slot for a third week running.
50 Cent's 'In Da Club' was at three, followed by R Kelly's 'Ignition' at four and Craig David featuring Sting with 'Rise & Fall' at five.
Other new entries on the Irish singles chart included Bon Jovi's 'All About Lovin' You' at 16, Buddy Joe' 'Klubbhoppers' at 21, 'Lately' by Lisa Scott-Lee at 24 and 'The Bhoys Are Back in Town' by Dance To Tipperary at 28.
In the UK, Girls Aloud also ranked number two as R Kelly held on to the top spot for a second week.
Girls Aloud will be joining Busted, Six, Simon Casey and Mankind as part of the line-up for Westlife's Lansdowne Road concerts on Friday 27 and Saturday 28 June.
