Aimee Teegarden keeps it chic in a brown leather Michael Kors jacket as she arrives at the 2010 Teen Vogue Young Hollywood Party held at Paramount Studios in Los Angeles on Friday night (October 1).

The 20-year-old Prom starlet joined costars Yin Chang, Nicholas Braun, Cameron Monaghan, Raini Rodriguez, and Janelle Ortiz on the red carpet. The girls were spotted hanging out at the Very Hollywood Michael Kors Eau De Toilette fragrance bar inside.

Aimee caught up with JJJ recently and dished that after the party, her exciting weekend plans included installing a water softener in her house.
