killed in a road accident this week - might not attend the star's memorial service, Mathosa's sister said on Wednesday.
"We're keeping in touch with him. He's in counselling.
.. he was a good friend to Lebo and nobody blames him for her death," Queen Mathosa told Sapa.
The driver, identified as "Nhlanhla" by The Sowetan newspaper, was reportedly in seclusion with family and friends to keep him away from media attention.
"He is still in shock and not ready to face the world, not at all," said a source.
Police spokesperson Andy Pieke said the man would not be arrested before investigations were complete.
He declined to name the man saying the media would have to get information from the driver's family and friends.
A reconstruction of the accident continued on Wednesday.
"We'll look into speed and try to determine the speed of the vehicle before the accident occurred.
We'll interview witnesses and check the position of the passenger and the car after impact," said Ekurhuleni metro police spokesperson Inspector Kobeli Mokheseng.
He said he doubted if speed was a factor in the accident and declined to comment on whether Mathosa or her driver were wearing safety belts. Mokheseng could not project when the reconstruction of the accident would be complete.
Meanwhile details of Mathosa's two public memorial services were finalised.
"There will be a service at Sandton Convention Centre on Thursday at noon and one at Benoni city hall at 8am on Saturday," said Mathosa's publicist Linzi Cowley.
Both services were open to the public.
"Lebo has a lot of friends in the music industry that want to pay respect to her," she said.
She could not confirm who would attend if any would pay tribute to Mathosa in song.
Mathosa's sister said the Kwaito and Rhythm and Blues singer would be buried on Saturday after the memorial service.
She did not disclose the location of the cemetery and said the burial would be attended by family members only.
"After the service - at Benoni city hall - the family will leave to go to the cemetery," said Queen Mathosa.
Mathosa, 29, was killed on the N3 Highway near Germiston on Monday morning.
It was believed her driver lost control of their Toyota Prado and crashed into a tree.
