Bieber is only 17 years old but he really sure know how to treat his girlfriend.  On Friday night Pop Star Justin Bieber treated his celebrity girlfriend Selena Gomez on a date at the Los Angeles Staple Center.  Not just any kind of date but a very private date.  They enjoyed a private screening of the classic movie Titanic in the 20,000 seat arena. 

They first enjoyed a concert at the Nokia Theater to see their friend Demi Lovato perform, then a nice steak dinner then after, the Titanic on the big screen at the Staples Center. Bieber got to use the arena as a gift from the Staples Center administration, for selling out three shows there.
