Mick Jagger stunned an audience in Spain on Tuesday by showing his nipples during a show after he noticed a blonde woman had taken off her top and flashed her breasts at him.

The 79-year-old singer was belting out the lyrics to his 1965 hit “(I Can’t Get No) Satisfaction” when he noticed the lady — who has not been identified but was holding an American flag — flashing him.

After a moment of contemplation, the Rolling Stones icon lifted his own shirt before returning to dancing and interacting with the crowd in Madrid.

The clip — which was posted on the singer’s Instagram — shows the blonde dancing to the music with her top down at her hips.

As the clip ends, viewers can see the woman, who was hoisted atop another attendee’s shoulders, begin to put on her shirt.

The Madrid show was part of a tour celebrating the 60th anniversary of The Rolling Stones. The band was also joined by Jagger’s partner, Melanie Hamrick, the ballerina with whom he shares son Deveraux Jagger, and his 23-year-old son, Lucas Jagger, whose mom is Luciana Gimenez.

Jagger and The Rolling Stones have performed in Italy, UK, Germany, Sweden, France, Austria, Belgium and The Netherlands as part of the anniversary tour.

The frontman has notably been enjoying life on the road, frequently sharing Instagram photos of his travels and stops as a tourist around the world.
