What pop-rock band is this?

Its driving me mad, its like a pop-punk band, with a black screamer, and i cant remember any song titles or the bands name. Think the word star or stars might be in a title or the bands name but that sme clutching at straws so i might be really wrong. One of the videos i saw was definately filmed at night...haha, i know its very vague, but its really driving me mad!
