The teen heart-throb portrayed Marius in the West End production for a limited run over the summer, and he returned to the role in London once more to mark the musical's 25th anniversary.
The show, which also featured Little Britain funnyman Matt Lucas, attracted celebrity fans including Jonas' brother Joe Jonas, as well as McFly star Tom Fletcher, and was beamed into cinemas across the U.K. and worldwide.
And Joe was full of praise for his sibling's performance. In a post on his Twitter.com page after the show, he writes, "Nick Jonas in LesMiz25 was perfection. He is so incredible. Congrats bro. Love you! Proud of you!"
