Joe Jonas must have really impressed Britney Spears!

The middle JoBro is joining Brit Brit for her entire European Femme Fatale tour, according to People.

Starting October 16, Joe will open for his childhood crush overseas. If you weren't official jealous of him before (you know, when he was dating Taylor Swift, Ashley Greene or Demi Lovato), the kid is now actually having a dream come true. He tells the mag:

    "She was the first girl I ever had a poster on my wall of, and her album was the first CD I ever bought. It's so funny to think I had that on my wall and here I am about to perform with her."


Seriously. Jealous.

Joe will join the "I Wanna Go" singer for her nine dates in Sweden, Germany, the Netherlands, France, Ireland and the United Kingdom. This is in addition to the announcement last week that he'd be opening for Britney's New Jersey show August 5.

His first solo album, Fastlife, drops October 11.
