A heartwarming video has emerged of a young woman's reaction when she receives tickets to see the Backstreet Boys as a surprise from her sister.

The footage, captured on May 7 at a home in the Bronx, NYC, USA, shows Jessie's sister Yvette telling her to read words written on cards she holds in order to discover the surprise.

Moments after, Jessie bursts into tears as she realises she is going to see her favourite band.

''I surprised my Jessie Wessie -who is Down Syndrome has severe thyroid problems and dwarfism - with tickets to Backstreet Boys. She's loved them forever,'' the sister later wrote online.

''I decided to record her expression not knowing she'd react this way. I just wanted to share her reaction because it really touched me and so did others when I showed them.''

''Every time I watch it it brings tears to my eyes and I thank God that I'm able to make her dream to see them in concert come true,'' she added.
