Jason WAHLER banned from FIANCEE'S Apartment after RACIAL slurs!!

Jason Wahler went to rehab last year after arrests for underage drinking and assault – and he hurled racial epithets at a cop.

Now, the 21-year-old former star of The Hills has been banned from fiancee Katja Decker-Sadowski's USC apartment, Us Weekly reports in its latest issue, on newsstands now.
The ban is the result of Wahler's use of racial slurs against a security guard on February 10 at Conquest's Tuscany, the apartment complex where Sadowski lives.
"He called him the N word," a source tells Us.
A Conquest rep adds, "Jason Wahler's racist remarks were uncalled for. He is no longer welcome in the building."
Wahler tells Us, "None of this happened."
