A family from Accrington in Lancashire and a nurse from Liverpool will be among the guests at the Royal Wedding between Prince Harry and Meghan Markle.
11 year old Madison Kennedy-Finglas, her family and her nurse Elaine O'Brien will be representing WellChild, a charity for seriously ill children, for which Prince Harry is Patron.
Lets find out what Madison and her mum Danielle think about going to the wedding of the year.!
Prince Harry was also presented with a pottery pig at the WellChild awards by a girl from Southport. The ornament was designed to look like him, with the addition of curly red hair and a suit and tie.
Olivia Ruston, who won a young hero award for caring for her severely ill sister, said: "I wanted to make him something to say thank-you for all the work he does for WellChild.
"He said he really liked that it looked like him."

Prince Harry was won over by a young boy from Lancashire who greeted him with a hug at an awards ceremony to recognise the courage of seriously ill children and their families. The Prince met with winners of the 10th annual WellChild Awards at the Hilton in Park Lane, central London.
Four-year-old Carson Hartley from Oswaldtwistle, who has a heart defect and is fitted with a portable ventilator, wasted no time in running straight up to the Prince and wrapping his arms around his legs.
The pair then exchanged a number of high fives while the Prince chatted to Carson's parents about his complex heart condition.
His mother Kirsty said: "We were worried he was going to high-five Prince Harry in the face he was so excited.
"Harry got down on his knees and had a big smile on his face while he was chatting to Carson, he couldn't believe how active he was despite all the conditions he has.
"He said he thought he was inspirational for still being so happy, but he also said that parents must be recognised too for how hard they work, which was really nice to hear."
The awards recognise the courage of children and young people living with serious illnesses as well as the dedicated families, nurses and doctors who care for them.
A special garden is being created in Manchester for a girl who suddenly lost her sight.
13-year-old Becky from Denton went blind when her optic nerve stopped working two years ago. The reason for this is still unknown and there is currently no treatment available to restore Becky’s sight.
Charity, WellChild is organising a garden transformation, which will enable Becky to spend time outside with her many rabbits and guinea pigs.
It's hoped regaining some independence will have a dramatic impact on Becky’s life and her family cannot tackle this huge task unaided. The transformation will also make it easier for Becky and her family to spend time together in the garden.
