Hairstylist Christian Marc tweeted this photo of Cyrus' latest hair escapade: a deep side-parted, super-slick pixie. Paired with the bold brows, we think we're in love. (Note to Miley: Keep this look! Pretty please?)

Beyonce went blonde! Well, sort of...

Ashley Benson went brunette! (For real.)

Anyone else feeling like a trip to the salon is in order this week?
