Last week, several gossip websites reported that Miley Cyrus' new boyfriend is actually Arnold Schwarzenegger's son, Patrick. The 'Bangerz' star and the model was seen leaving the former's apartment the morning after partying at the Roosevelt Hotel for Halloween.

The rumored new lovers, who allegedly have been dating for months now without anyone knowing, are reportedly just keeping things casual at the moment. This news comes as a surprise since Schwarzenegger previously said that he "had his eye on Miley" since 2011.

On the other hand, E! News reported that the new couple are not yet "official" and are just dating casually without Patrick Schwarzenegger being labelled as Miley Cyrus' new boyfriend. Right now, they are just "really good friends."

Is their relationship so open that the 21-year-old can go on dates with other girls?

According to Perez Hilton, the University of California student was seen having lunch with a blonde "who is NOT Mileybird" last Sunday. However, the blonde girl could have just been a friend or cousin.

Did the attraction fizzle out as soon as it became public? Or is Miley Cyrus just too busy right now to accompany her alleged new beau for lunch?

Meanwhile, Schwarzenneger's mother, Maria Shriver, reportedly doesn't approve of the 'Wrecking Ball' hitmaker dating her son. According to Hollywood Life, Shriver "disapproves of the relationship that Patrick is starting with Miley."

Her ex-husband, however, doesn't have the same qualms.

The source further revealed, "She is getting some support from other family members as well, but she isn't getting the same support from Arnold because Arnold is happy with whatever Patrick gets himself into in the girls department."

Whatever the case, we will just have to wait and see if the pair will reveal themselves again.

Do you think Patrick Schwarzenegger is really Miley Cyrus' new boyfriend? What do you think of this blossoming relationship?
