The funeral service for Kimberly O'Connor, the 16-year-old who died in a car crash last week in Cork city has been told that she was a superstar whose death has left everyone who knew her heartbroken.

In a tribute read by her sister Shannon, her mother Jennifer wrote that her heart is completely broken and she will never be the same until she is with her again, but takes some comfort in the fact that she is now with her father Mark who died when Kimberly was just four.

She said Kimberly made her the proudest mum in all the world with all she did, especially "her beautiful singing which would make the hairs on her head stand up."

She said: "I will miss everything about you, the pain of losing you is unbelievable - baby Cory & Tori (niece) will always know you - your name and memories will always be spoken in my house everyday."

Addressing the packed congregation in St. Mary on the Hill Church, parish priest Fr Gregory Howard said that since word of the crash spread, a cloud has hung over Knocknaheeny.

"Nothing prepared us for that. She was too young, too fragile, still so unprepared to give up life."

He said Kimberly "was given many talents which she used generously and unselfishly. She was charming, a total extrovert.  

"She spread joy and happiness wherever she went. She empathised with people and was always a voice for her fellow classmates. She had lots of sass.

"This is a life fully lived, talents used for the benefit of others."

Among the symbols of her life brought to the altar was a painting Kimberly did while in school at Terence MacSwiney Community College, a Hope Foundation t-shirt, eye lashes, a bottle of tan and a microphone.

Her mother, sisters and aunts flanked her white coffin as it was led from the church, while students from the Super Star stage school formed a Guard of Honour.

She was laid to rest in St Catherine's Cemetery in Kilkully.

A 17-year-old boy who was also injured in the crash remains in a critical condition at Cork University Hospital.

A third teenager, the 16-year-old driver, was treated at the time for non-life threatening injuries.

Last week, Kimberly's school - where she was a transition year student - opened during the midterm to offer support to students and teachers affected by her death.
