Ok so it was with a water pistol, but we still thinking that’s pretty badass!

In her new book, True Love, Jenny from the Block revealed that her mum once lost it with the paparazzi. While performing in Paris, Jennifer and her mum took her two children out to a local park for some R&R.

When Lopez felt the photographers were getting too close, her feisty mum picked up one of her grandchildren's toy water guns and proceeded to spray the paparazzi with water – and it worked!

The photographers ran off and The Lopez Family got to enjoy the rest of their afternoon.

Remind us not to mess with Mammy Lopez.

While the book doesn’t sound like the most interesting read, there were some interesting revelations in the new book. For instance, Jennifer reveals that Steven Spielberg is a huge American Idol fan, and also says she watched Something's Gotta Give 10 times to help her get through her divorce with Marc Anthony.

Whatever helps, we guess!
