Iron Maiden and Aerosmith have not collaborated in real life. While both bands are well-known rock acts, they come from different eras and have distinct musical styles.

Although the two bands have not collaborated, Aerosmith and Iron Maiden have shared the stage together. They both performed at the Appetite for Destruction Tour which lasted for 16 months and headlined shows across four continents. During this tour, they opened for bands such as The Cult, Mötley Crüe, Alice Cooper, Iron Maiden and Aerosmith. Unfortunately, I don't have any information on whether they have performed together after that tour.
