Shakira and Jennifer Lopez were not paid for their controversial halftime performance at Super Bowl LIV, but the appearance could still prove lucrative for the superstar singers.

The NFL never pays the halftime show performers an appearance fee, though it covers the estimated $10 million in expenses to stage the massive performance, including union scale for crew.

However, artists still jump at the chance to perform at the Super Bowl, which boosts their visibility and essentially serves as a massive commercial for their music.

According to Billboard, combined music sales for Shakira and J-Lo rose 843% in the day following their performance.

Shakira’s Whenever, Wherever was released 19 years ago but shot to the top of the iTunes Top 100 chart on Tuesday.

It’s a better chart position for the song than when it was originally released, when it peaked at number six on the Billboard charts in the early 2000s.

Joining it in the top ten this week were the Colombian singer’s other former hits Hips Don’t Lie (#3), Waka Waka (#5) She Wolf (#8).

Shakira also capitalized on the Super Bowl buzz by announcing on Monday that she would be embarking on a world concert tour in 2012.

As for Lopez, her collected songs sold 8,000 downloads on February 2, up 800% from a little under 1,000 sold on February 1, according to Billboard.
