Jason Wahler of MTV's 'The Hills' and 'Laguna Beach' is serving 30 days behind bars for assault and underage public drunkenness.
The reality star reported to a jail on Thursday in Issaquah, Washington.
Ruth Bowman, spokeswoman for the Seattle City Attorney’s Office, told People magazine he "could get out in 20 days for good behavior."
Wahler, whose additional charge of criminal trespassing was dropped, recently completed a stay in rehab.
