Leah Washington, who lost a leg after the Alton Towers rollercoaster crash, celebrated her 18th birthday on Tuesday night with boyfriend and fellow victim Joe Pugh.
Washington was one of five people seriously hurt when the Smiler ride collided with an empty one halted on the track on June 2.
The teenager, who was on a date with Pugh at the time, later had her left leg amputated above the knee and Pugh, 18, suffered two shattered knees. Vicky Balch, 20, also had a leg amputated as a result of the accident.
Washington posted a photo of her and Pugh enjoying a night out for her birthday on Instagram, and later wrote on Twitter that she had "such a good birthday".

Balch wasn't so lucky spending her 20th birthday last month in a critical condition.
