There may be a few hungover stars at tonight's Grammy Awards -- because last night, there were some pretty amazing pre-parties all over town!

The biggest of the bunch had to be Clive Davis' annual bash, which attracted celebs and singers like Rihanna, Miley Cyrus, Taylor Swift, Lorde, Jennifer Hudson, Robin Thicke, The Osbournes and more.

Swift seemed to be enjoying herself, dancing up a storm with all her famous BFFs, but it was Miley who stole the show.

Cyrus took the opportunity to debut her new look, showing up for her performance with a blonder 'do.

Check out the gallery above to see all the pics from inside the soiree. And be sure to come back later today around 3pm PT for all the red carpet photos from this year's Grammy Awards!
