Joe Jonas' Fantasy has become a reality - he will be supporting Britney Spears on tour.
The middle Jonas brother had posters of the superstar on his wall, and readily admits to having a childhood crush on her.
Now he has announced that he will open the European leg of her Femme Fatale tour from October 16.
"It's a dream come true," he told People.
"She was the first girl I ever had a poster on my wall of, and her album was the first CD I ever bought."
Joe – who is promoting his upcoming solo album Fastlife – added: "It's so funny to think I had that on my wall and here I am about to perform with her."
He later tweeted: "It's official. Performing on the European leg of @britneyspears tour."
The 21-year-old singer described Britney, whom he first met at an awards show a few years ago, as "a very sweet lady".
He will join the tour on August 5 for one date in the US, before opening 10 shows in Europe.
"I'm really looking forward to being part of this," Joe continued.
"I'll be playing more music than I have the past few times I've performed live so far.
"It's going to be really fun to perform some of my music from the album."
