Pontardawe tree crash: Matthew MacMillan and Mitchell Evans tributes
The families of two men killed when a car they were travelling in came off the road and collided with a tree in the Swansea Valley have paid tribute.
The crash involving a silver Renault Clio happened on the A474 Neath road at Fforest Goch near Pondardawe at about 19:00 GMT on Tuesday.
Matthew MacMillan, from Briton Ferry, and Mitchell Evans from Cimla, Neath, were both 21 years old.
A third person who was in the car is still in hospital, police say.
The family of Mr MacMillan, who was known locally as Millan, called him a "legend" and said he will be in their thoughts forever.
In a tribute issued through South Wales Police, the family said: "He was a beautiful, loving, handsome boy who was a free spirit.
"He was a loving brother of Siobhan, Christopher and Ellouise and a doting father of Macey and her mum Becky, special uncle to Harvey and grandson of Paul and Gloria and will be missed by all of the family.
"When he smiled it was infectious and everybody smiled with him. Matthew had so many special friends, far too many to mention."
His mother Sian added: "I have always loved him and always will and I know that you're looking down on us from your cloud with your cheeky grin."
Alisa and Ieuan Evans paid tribute to their son Mitchell.
"Our handsome boy, our little prince, our world has been turned upside down and our hearts ripped out," their statement said.
"You were an amazing son, brother and grandson. You were royalty to us and our lives will never be the same again."
Family liaison officers are continuing to support both families.
Police are appealing for witnesses, including anyone who saw the collision, stopped to provide assistance, or anyone who may have seen the vehicle being driven beforehand.
Anyone with information should contact the South Wales Police roads policing unit on 101 or Crimestoppers on 0800 555 111.
