Lawson came on Wednesday's show because we got the first play of their new single!
It's called Brokenhearted, it features B.o.B, and it's bloomin' brilliant!
The boys came on the show to talk about the single, playing at the Summertime Ball, and whether it would be a good idea to get some gold teeth...
We love having the Lawson boys on, they're always a laugh, and we proper love the single too!
