Spanish prosecutors have asked for eight years in prison for Shakira

The singer, who has sold more than 80 million records worldwide with hits like "Hips Don't Lie," rejected a settlement offer from the prosecutor's office earlier this week to drop the case.

He is accused of failing to pay taxes between 2012 and 2014, a period in which Shakira says she did not live in Spain. Prosecutors' documents, seen by Reuters

Claim Shakira usually lived in Spain between 2012 and 2014 and bought a house in Barcelona in May 2012 home for herself, her partner and their son, born in Spain in 2013.

Shakira's representatives cited an earlier statement sent Wednesday saying she is "absolutely confident of her innocence" and that she considers the case "a complete violation of her rights."

Terms of the previous settlement offer were not disclosed. The 45-year-old singer - dubbed the Queen of Latin Pop - said she initially paid the 17.2 million euros the Spanish tax office said

She owed and claimed she had no outstanding debts with tax authorities. The latest development in the tax case comes a month 

After Shakira and her husband, announced their separation. Shakira, 45, and PK, 35, have been together since 2011 and have two sons together.
