A 10-year-old girl has come up with the winning design for an emblem for the Queen's official 2012 Diamond Jubilee.
Katherine Dewar's artwork was picked from tens of thousands of entries in a nationwide competition run by CBBC's Blue Peter.
Her design of a crown above the Union Flag with diamonds down either side, will appear on everything from official Jubilee posters to tea towels!
Katherine said she was really excited to win.
Katherine's design will be used on posters, flags and even tea cups!
"I'm looking forward to seeing people waving flags with my design on to celebrate the Queen's Diamond Jubilee," she said.
Katherine's design was chosen by a panel of judges that included Blue Peter presenter Barney Harwood and Tracy Beaker illustrator Nick Sharratt.
The competition was split into three age categories - six to eight-year-olds, nine to 11-year-olds and 12 to 14-year-olds.
The creators of the top 30 designs across the competition have been invited to a special tea party at Buckingham Palace to celebrate their achievements.
