No Directioner would want to miss this year's iHeartRadio Music Festival as three of their boys - Harry Styles, Niall Horan and Louis Tomlinson - will all be there to make the best party ever!
Could this be the reunion they've all been waiting for? Liam is MIA, though.
The two-day event will take place on Sept. 22 and 23 in Las Vegas, and will also feature acts from Coldplay, The Weeknd, Pink, Miley Cyrus, Thirty Seconds To Mars, David Guetta, Kesha and more.
Do you want Harry, Niall and Louis to perform together? Send us a comment!
