Posh would be proud.

"Now that I'm blonde I gotta give duck lips in every photo," she tweeted.

19-year-old Miley made the decision to go for a brighter blonde look for summer, which we think is a damn sight better than the long brown waves she had in her younger years.

Miley has recently been getting irritated at paparazzi for invading her privacy. Last week she took to Twitter to vent her frustration: "I hate paparazzi with a passion. disgusting pigs. (no offense to pigs)"

Fans rushed to support her, retweeting her message over 17,000 times.

She followed that tweet up with another message aimed at the 'shady and scary' paps, tweeting: "How is it legal for men I've never seen before to sit in front of my house and then follow me around! So shady and scary."

Miley through the ages
