Good Charlotte rocker Benji Madden has laughed off reports he's split with his fiancee Sophie Monk. The guitarist - whose brother is frontman Joel - proposed to his Australian girlfriend last year (07) but the couple sparked rumours of a break-up after Monk returned to her native country alone after Christmas. However, the musician's publicist has blasted the reports, according to celebrity blogger Perez Hilton, releasing a statement saying, "Benji Madden and Sophie Monk are together and very happy."
