I’ve promised myself to never fall in love with boy bands again after N’Sync and Backstreet Boys disappointed me years back, but omg… these boys from Jack the Lad Swing are gorgeous and actually really good!

Aston, JB, Marvin and Oritse couldn’t wait for people to hear what they’ve been up to in the studio over the past few month, and omg, what a sexy performance they gave the audiences at Leeds Party in the Park, Leeds, UK!

Pictured above, band members Marvin and Aston goes topless for the thousands of cheering fans. See more shirtless photos of JLS after the jump.
