Abreu first rose to fame in Finland after placing as the runner-up in the third series of the Finnish singing talent show Idols in 2007.

She has certified record sales surpassing 190,000 copies, which places her also among the 100 best-selling music artists of all time in Finland.

As a young child, Abreu spent some time residing in Portugal, and speaks fluent Portuguese, Spanish, and English in addition to Finnish.

Abreu's performances attracted heavy public support, however, during the top 5 results show, she landed in the bottom two contestants alongside Panu Larnos.

Abreu survived the elimination and made it through to the live grand finale at Helsinki Ice Hall with fellow contestant Ari Koivunen, who sang exclusively in the heavy-metal genre.

On 5 April 2007, Koivunen won the crown as the third Finnish Idol with 57% of the public vote, with Abreu declared as runner-up.

Following her participation in Idols, Abreu was signed to Sony BMG Finland and her Latino-inspired, debut single "End of Love" was released in July 2007.

Her self-titled debut album, Anna Abreu, was released a month later on 22 August and was certified platinum within its first week after going straight into the chart at number one and selling 30,000 copies.

Produced by Patric Sarin and Rauli Eskolin, the dance-oriented song marked a creative step away from the pop and RnB roots of Abreu's debut album.

that Abreu earned over 145,000 euros in 2008 through a combination of album sales, touring and public appearances, making her one of Finland's highest-earning singers.

In late August 2010, Abreu announced via her official Facebook page that she had begun work on her fourth album, Rush.

In 2011, Abreu started dating Finnish professional snowboarder Lauri Heiskari and the couple became engaged in July 2012,[9] marrying on 20 June 2013.
