Chiquis Rivera's debut project, Ahora, sold 7,000 copies in its first week to score the top spot, a feat no female artist has achieved since her late mother's posthumous disc, 1 Vida-3 Historias: Matamorfosis - Despedida de Culican, was released in December (14).

The success of Ahora also makes the mother/daughter duo the first to each score number ones on the chart, and only the third parent/child in Billboard history to take solo discs to the top - Vincente and Alejandro Fernandez and Julio and Enrique Iglesias are the only other superstar relatives.

In addition, Chiquis' chart-topper makes the Riveras the only family to have three individual members hit the top spot as solo acts - Jenni's brother, Lupillo Rivera, previously enjoyed a number one on the Top Latin Albums list.

Jenni Rivera was killed in a plane crash in Mexico on 9 December, 2012, aged 43.
