Former singer, who initially started out presenting children's programmes before branching out to sports journalism, going onto establish herself as the voice of sport on Radio Cymru.
After hosting a string of entertainment titles for S4C - including her own short-lived chat show - she can now be heard in English hosting the late show on BBC Radio Wales.
She is not to be confused with Sian Eleri.
Eleri played rugby for both Lampeter and Cardiff University, where she captained the woman's team before being forced to retire through injury.
In 1995, she became Radio Cymru's first female rugby correspondent.
