Blake Shelton Goes After Adam Levine's Pink Hair on Twitter -- See All the Memes!

Blake Shelton was tickled pink over his pal Adam Levine's new 'do.

Levine debuted his pink hair on The Voice's knockout episode, which also had Miley Cyrus as a key adviser. While she too is known for her outlandish looks, the "We Can't Stop" singer opted for a high, blonde ponytail -- perhaps a homage to Voice mentor Christina Aguilera's "Genie in a Bottle" days.
