TMZ got Kings of Leon singer Caleb Followill on camera yesterday.  Caleb was with his daughter and model wife Lily Aldridge.  Telling the camera man "I'm just trying to get better,"

On Monday, the Kings of Leon scrapped their tour in the wake of a disastrous Dallas show during which Followill repeatedly complained about the heat and then abruptly left the stage after announcing to the crowd at the Gexa Energy Pavilion, "I'm gonna go backstage and I'm gonna vomit. I'm gonna drink a beer and I'm gonna come back out and play three more songs."

He never reappeared, leaving his bandmates to apologize to the audience. Following the show, KOL bassist Jared Followill took to Twitter to express his frustrations, writing, "There are internal sicknesses & problems that have needed to be addressed. I can't lie, there are problems in our band bigger than not drinking enough Gatorade."
