Cheryl Tweedy found it "heartbreaking" when Liam Payne's final TV show was released on Netflix.

The 31-year-old singer / songwriter filmed Building The Band before his tragic death following a fall from a balcony in Buenos Aires, Argentina last year and Cheryl, 42, the mother of his eight-year-old son Bear, has reportedly found it difficult to deal with the release of the show.

A source told the Mirror: "It is very sad for Cheryl. She's very proud that Liam's final project is now available for the world to see, but obviously it's heartbreaking, too, after Liam's death. It's a poignant reminder to Cheryl - and to his fans - of how much more Liam could have done with his life. But that potential was tragically cut short."

Cheryl - who dated Liam from 2016 to 2018 - is said to be worried about how the show will affect Bear.

The insider explained: "He had so much going for him, as well as being a devoted father to Bear. It's another reason why Cheryl wanted to continue with her own TV career - to show Bear that there is life after losing Liam, that you can be strong and that he can pick himself up. He can be anything he wants to be in life."

Building The Band host AJ McClean paid a poignant tribute to Liam at the beginning of the first episode.

He said: "When we came together to film Building The Band, we never imagined we'd soon be saying goodbye to our friend, Liam Payne.

"Liam is a guest judge in later episodes and, through his presence, we see his deep love for music and his unwavering commitment to helping others find their voice. It's through that spirit that we dedicate this series to Liam and his family."
