Demi and Ashton: An age defying romance
When the couple jetted off for a romantic break in Mexico over Valentine's Day, the world's media went into overdrive – yet again - with speculation that the pair had become engaged.
It wasn't true – but there was no denying the couple were serious about one another.
"I love being with her. She makes me a better person," Ashton told chat show queen Oprah Winfrey.
Demi later said: "I knew it had the potential to be something special right away. It was like meeting somebody that I've just known where you just recognize one another.
It was so disproportionate, the level of emotion we were experiencing to the time we had spent together".
