The 4th Dimension tour kicks off in March, and despite already adding several extra dates earlier this month, the boyband have now announced three more performances after experiencing "phenomenal demand" for tickets.
The new dates will see the 'She Makes Me Wanna' group travel to Manchester's MEN Arena on April 20, followed by London's O2 Arena the following evening, and also Glasgow's Braehead Arena on April 24.
"We can't wait to headline our second arena tour," JLS said in a statement. "It's been an incredible few years for us and the 4th Dimension tour is going to be amazing.
"We're really excited to perform tracks off our brand new album as well as fan favourites. We are working really hard to make this tour a huge experience for our fans. There will be some surprises in store!"
JLS recently revealed that they are hoping for "magic" and "flying elephants" during their tour.
The new dates in full:
- April 20 - Manchester, MEN Arena
- April 21 - London, O2 Arena
- April 24 - Glasgow, Braehead Arena
