Nonstop was a Portuguese girl group, created through TV reality-competition show Popstars, in 2001. Nonstop achieved notable success with their debut album, Nonstop, and single, "Ao Limite Eu Vou".

Songwriter and producer Eliot Kennedy, who had previously worked with bands like the Spice Girls and Take That, once said "they are probably the best group I have worked with. Their voices are so good!"

Following its success in Australia, Germany and the U.K, the dream catcher reality-show Popstars arrived in Portugal via SIC in 2001, looking to create a five-piece girl group.

Over 1,200 girls attended auditions, held in the cities of Coimbra, Porto, Faro and Lisbon, with hopes of securing a spot in the band.

During auditions in Faro, Liliana Almeida [pt] saw her participation be denied due to age restrictions - she was only 17. Almeida would eventually make it to the last day of auditions in Lisbon, which coincided with her 18th birthday.

By April 4 2001, the five finalists had been chosen: Andrea Soares, Ana Rita Reis, Fátima Sousa, Kátia Moreira and Liliana Almeida were to become Portugal's Popstars. The girls named themselves Nonstop.

Nonstop's first single, "Ao Limite Eu Vou", was produced by Steelworks duo Tim Woodcock and Eliot Kennedy. The song became one of the biggest hits of summer 2001 in Portugal, reaching the top spot on the national music charts.

Nonstop's self-titled debut album was released on July 16, 2001. The album went to sell over 30,000 copies and was certified Gold.
