The reason behind Adele's weight loss revealed

A source has revealed why UK singer Adele lost weight with the aim of keeping it that way.

The source told PEOPLE that the singer decided to lose 7 stone weight through a diet overhaul because of her 7-year old son, Angelo.

According to the source, Adele wanted to be "the healthiest mum possible".

The source told People: "She got to the point where she didn’t feel great. She knew she had to change something, because she wants to be the healthiest mum possible.

"Her whole focus during the weight loss journey has really been all about how she can be healthier and how can she treat her body better. It was never about losing weight."
