According to a Bulgarian music source POPCORE.TV, MBLAQ's "Mona Lisa" has surpassed Selena Gomez, Chris Brown & Nicki Minaj, claiming the #1 spot for two months straight! Member G.O. thanked his fans via his Twitter page saying, "#1 on Bulgaria Music Charts for 60 days in a row!!! Thanks to Bulgaria" "Mona Lisa" has consistently worked its way up to the top, as it was #9 on August 15th, and became #3 on the 16th. The song is also #1 on Germany's Asian music charts, and this accomplishment is highly praise-worthy considering the boys have never even performed in Europe. MBLAQ's fame however, does not stop in just Asia and Europe. MBLAQ is currently in South America for MBC's 2011 K-pop Cover Dance Festival and fans there cannot get enough of the boys. A video of fans awaiting MBLAQ in Sao Paulo at the airport and at their hotel, screaming their names and singing along with their songs were uploaded via Youtube and is receiving much attention.
