People's recent exclusive cover story on Brad Pitt and Angelina Jolie's infant twins was a blockbuster, selling 2.6 million copies, making it the 4th highest newsstand seller in the mag's history, sources tell ET.

The issue featuring babies Knox and Vivienne, which is the highest selling issue in the past seven years, sold slightly more than People's exclusive cover of Brad and Angelina's daughter Shiloh in 2006, which sold 2.2 million copies.

The only People issues that sold more on newsstands were on the topics of September 11th, Princess Diana's death and the death of John F. Kennedy Jr.
