The 27-year-old Irish singer returned home from Los Angeles to join the line-up for the Sons And Daughters celebration, where she sang a medley of hits from her band Girls Aloud. But she says the gig pushed her already-strained vocals to its limit and now she is literally speechless, reported Daily Express online.

In a post on Twitter, she writes, "My voice has been going for a week. Since yesterday gone! Even the throat lozenge I almost chocked (sic) on stage couldn't help."

Coyle was due to reunite with her Girls Aloud bandmates to begin rehearsals for their upcoming 10th anniversary tour but the first run-through was postponed due to travel issues prompted by the blizzard-like conditions - giving the singer an extra day to recover from her illness.
