Happy birthday, Queen Elizabeth!

The monarch turns 86 today, and it's a very special anniversary for Her Majesty in other ways: she's currently making her Diamond Jubilee in honor of her 60 years of rule.

In celebration on Saturday, Britain's Royal Navy fired a 21-gun salute. But the queen gets two birthdays every year: her actual celebration today, and then an official birthday, celebrated in June with a military pageant.

In honor of the queen's big day, we've rounded up some shots of Her Majesty meeting some of our favorite people, from Jennifer Lopez to Carla Bruni. (And remember that time she met Gaga?)

Check it out below!
