'A special graduation gift and memory with my girl,' Brooked penned in an Instagram caption along with a ladybug emoji.

She went on: 'I’m so proud of you, I love you more than words can say.'

Brooke is still recovering after recently suffering a harrowing leg injury and subsequent staph infection.

She broke her right femur after she fell off a balance board whilst at a gym in New York in January, and after undergoing two surgeries to insert metal rods and plates into her leg, she developed a very serious staph infection which required her to return to hospital for further emergency surgery. 

Brooke recently said she feels lucky to still be here.

She said: 'There's so many things that could've happened. I just feel so lucky to be alive.'
