Lebanese-Colombian singer Shakira underwent questioned at a Barcelona court on Thursday over the alleged evasion of $16.3 million in taxes.

The 42-year-old singer and one of her advisers are accused of tax fraud for not paying her taxes in Spain despite being a resident between 2011 and 2014.

However, the case only includes the period from 2012 to 2014 given that the timeframe to prosecute alleged tax violations in 2011 has expired.

Prosecutors claim that while Shakira moved to Spain in 2011, her official tax residency remained in the Bahamas Islands until 2015 when she started paying taxes in Spain.

Shakira's defense team insists that the singer had earned most of her money in international tours and did not live more than six months a year in Spain as the taxation law requires.
