The best friend of a teenager who was killed when she was hit by an out-of-control Lamborghini has penned a touching tribute from her hospital bed.

Jordyn was taken to Flinders Medical Centre with non life-threatening injuries and remains there for treatment.

The teen shared a tribute to Sophia to Instagram from her hospital bed on Monday, describing the keen volleyball player as a 'strong, beautiful girl'. 

'Every single piece of my heart goes out to this strong, beautiful girl that I will love forever and always,' she wrote alongside a selfie of her and Sophia.

'Words cannot describe how much I want to change what has happened. You will be forever loved in everyone's hearts and never forgotten.'  

Friends of the duo were quick to point out Jordyn's own strength and offer their support.  

School friend Daisy Page, 16, said Sophia and Jordyn had been best friends and that the pair were 'inseparable' and the 'nicest girls'.

'They always put other people before themselves. [They were] really caring, funny and really good at everything,' she told The Advertiser. 

'We'll always remember all the happy memories we had of her,' Daisy said.

Piper Window, who attended the same school as Sophia, described her as 'really caring' as well as 'smart and sporty'.
