Lil' Wayne was everywhere in 2007. If he wasn't onstage or on the radio rapping one of his songs (like "Fireman"), he was a guest on someone else's chart-busting hit. His Teflon-coated image seems to repel the negative rumors about his personal life, even when they come with photographic evidence, such as a picture of him kissing a man on the mouth last year. More recently, Wayne issued a warning to rappers who might challenge him: "No, I'm not gonna rap about you, man, I will murder you, your family, your child, a newborn." The Stop the Violence tour, featuring Lil' Wayne and Cassidy, comes to the Landmark Theater this Friday at 7 p.m. The rapper also has a court date in Arizona on Jan. 25, stemming from a recent arrest in Yuma. A representative for the Landmark confirmed on Thursday that the concert will go on as planned.Tickets are $45. Call 646-4213 or visit www.ticketmaster.com.
