Here are five facts:
Edele is the younger sister of Boyzone's Shane Lynch.
B*Witched achieved huge success in Europe and the US with eight Top 20 singles. They toured America alongside N'Sync and Britney Spears. B*Witched reformed in 2012 for The Big Reunion and performed their old material at a number of concerts.
Edele fell out with her band member Sinead, who she had been best friends with for 10 years, over shared lead vocals. Twins Edele and Keavy cut ties with their former band mate and left the group - but they're all friends again now, as Big Reunion fans will know.
The singer has written songs for Girls Aloud and Sugababes.
She met her husband Michael Barrett in 2005 after being set up on a blind date. They got married a year later and have three children together. Aww!
