Happy 23rd Birthday, Kevin Jonas!

Kevin Jonas has a lot to celebrate this weekend.

The eldest Jonas Brother turns 23 on Friday, and while there will surely be a party for KJ, the brothers Jonas aren’t taking the weekend off for festivities. They’re set to play a concert in Sao Paolo, Brazil, on Saturday night as they wind down their international tour.

So, join Celebuzz in wishing Kevin the happiest of days. Leave your birthday wishes in the comments section!
