X Factor star Jake, girlfriend Danielle and her mum Michaela donned their walking shoes to take part in Shine Night Walk - Cancer Research UK's night time walking marathon.
Jake followed the route of London's most iconic landmarks as he took to the streets to raise vital funds for life-saving research to beat cancer, which is a cause close to his heart.
He and Danielle walked past landmarks including St Paul's Cathedral, Big Ben and The Shard.
Jake said: "Having lost my brother and father to cancer, I know the devastating impact it can have on families and loved ones.
"I'm so proud to be supporting Shine Night Walk and be part of the thousands of people coming together to light up London tonight."
He added: "Too many of us have been affected but by all rallying together tonight and pounding the pavements, we can make a real difference and help beat cancer."
Shine Walk first started in 2010 and so far the event has raised £18 million. In 2015 Cancer Research UK hopes the event will raise almost £5 million to help fund the charity's pioneering research.
