There are a few names in Hollywood that we are always looking out for. As such, everywhere Mischa Barton goes will be closely followed. It comes as no surprise that the popular Harley Viera-Newton and Cassie Coane 21’st birthday party seemed to be quite a hit amongst many youngsters. This fun event was complete with funky birthday favors including star shaped sunglasses, fancy headwear, and custom printed t-shirts. This Modelinia sponsored get together saw all the right people gather including the Olsen sisters amongst others. One thing’s certain, they all looked absolutely stunning and if images speak a thousand words they surely did seem to have fun.
