The 'She Makes Me Wanna' boys have had their wrists slapped.
JLS have been cautioned by LA cops for crossing the road in the wrong place.
Police officers spotted Aston, JB, Marvin and Oritse jaywalking so hollered through their megaphone and gave the boys a telling off.
The guys were let off with a caution according to The Sun and can now get on with making some more brilliant music, which is the reason they're in the US in the first place.
Their current single 'She Makes Me Wanna' is still No. 1 on the Vodafone Big Top 40.
