Amy Winehouse's dad Mitch admits 2017 has been one of his toughest years since his daughter's death

Mitch shared: "We think about her every day. In fact, we think about her every minute of the day."

Amy would have been celebrating her 33rd birthday on September 14 and Mitch confessed that the landmark date hit him "very hard" this year.

Speaking to PEOPLE, Mitch explained: "I don't know why but this year her birthday hit me very hard. I don't know why but it was very tough."

However, Mitch is pleased that he's been able to continue Amy's legacy through the Amy Winehouse Foundation, which works to prevent the effects of drug and alcohol misuse on young people.

He said: "She was a really charitable girl, so we are really just continuing what she would have done."

Despite being one of the world's best-selling artists, Amy used to make food and socialise with homeless people in London.

And Mitch is proud that the foundation has been able to follow in her footsteps by helping people less fortunate.

He recalled: "Amy used to take people off the streets and feed them.

"She would make them all tea and sandwiches and go out and play football with them. Amy was just a very caring person."

Meanwhile, Mitch recently revealed that Lady Gaga will record one of his daughter's songs to raise money for her foundation.

Mitch said: "We've got this new YouTube channel where stars all over the world are going to do an Amy track and however many hits we get after the first two million, we start making money for the foundation.

"Leona Lewis is going to do one, Lady Gaga will do one, and a few other stars. Hopefully it's going to be a source of revenue for the foundation."
