Janelle Monae had a ball over the weekend for her bestie's birthday and she decided to share the moment with the world.

The "Tightrope" singer-songwriter attended a Pajama jam for her good friend, and the theme — sexy Elves.

"we take #elfies," wrote Monae on one photo, and on another, "HBD to my crazy bestie @mykalmonroe! I truly have the best times when you are there. Love you to pieces B. #pjammyjam #herbdayparty #sagitarriusgirls"

We would of loved to crash that party!
