Victoria Justice's Nickelodean Star Boyfriend Arrested For DUI

Rottman, who starred in "Gigantic" but may be even more famous for dating Victoria Justice, jumped the curb as he was driving in Hollywood. His bad luck ... cops saw it all, pulled him over and then
smelled a strong odor of alcohol ... so say our law enforcement sources.

After giving Rottman a field sobriety test, they arrested him on suspicion of DUI.

We're told Rottman blew a .19 ... well over twice the legal limit.

He was taken to jail, booked and released a few hours later without having to post bail.
