Avril's Birthday Blitzed

9/21/2007 9:40 AM PDT
Avril Ramona Lavigne celebrated her 23rd birthday a few days early last night at Koi -- and invited paparazzi to join in the festivities.

Lavigne, who's known around TMZ for spitting at photogs instead of posing for them, was actually friendly with paps outside the sushi den, and included them in her b-day scrap book.

Not only did a pink tiara-wearing Avril pose for pics, she also took selfies with the photogs and even a few shots of them alone. Who is this pink-streaked girl and what has she done with the real Lavigne?! They're the spitting image of each other!
