In 2007, Rubio recorded the song "Nena" as a duet with singer Miguel Bosé, from his album "Papito". "Nena" became a major hit in Mexico, peaking at number two for several weeks. It was also nominated for "Record of the Year" at the 8th Annual Latin Grammys. Rubio embarked on her second world tour Amor, Luz Y Sonido in 2007. In October, the Spanish edition of "Cosmopolitan" magazine featured her apparently naked underneath a red, white, and green sheet. A government probe was open about whether or not she had desecrated Mexico's flag. The Mexican government said she may have violated an article in the National Flag, Shield and Anthem Law, which states that "private individuals will give the appropriate respect to the national symbol and handle it with care". The offense can be punished by fines ranging from $45,000 to $50,000 MXN (Mexican pesos) and jail time of up to 36 hours. However, in a published report, her mother, Susana Dosamantes, said that the artist did not authorize such photos. In 2008, Rubio participated in the mega event ALAS, developed simultaneously in Mexico and Argentina. Rubio performed in Buenos Aires in front of 180,000 people, along with Shakira, Calle 13, Mercedes Sosa, Alejandro Sanz and Gustavo Cerati.
