Shawn Mendes knows how to "Treat You Better"; well, that's what he's claiming on his new track. Released today, it is the first single from the Canadian artist's forthcoming as-yet-untitled sophomore album, due out in September.

The plucky guitar-based pop tune finds Mendes playing Mr. Steal Ya Girl as he sings, “'Cause I know I can treat you better than he can / And any girl like you deserves a gentleman / Tell me why are we wasting time on all your wasted time when you should be with me instead."

Last week, the singer teased the track's accompanying music video. No word on when that will be released, but in the meantime, kick your no-good boyfriend to the curb and sway to "Treat You Better" above!
