c++11 Singleton is creating new instances

This is my singleton

class MySingleton {
private:
    int myNumber;
public:
    static MySingleton &get() {
        static MySingleton instance;
        return instance;
    }

    int getMyNumber() const {
        return myNumber;
    }

    void setMyNumber(int myNumber) {
        MySingleton::myNumber = myNumber;
    }
};

and this is the code to test it

MySingleton t1 = MySingleton::get();
t1.setMyNumber(6);
printf("t1: %d \n", t1.getMyNumber());

MySingleton t2 = MySingleton::get();
printf("t2: %d \n", t2.getMyNumber());

Now the output I get is

t1: 6 
t2: 0 

but te expected result would be

t1: 6 
t2: 6 

It looks like MySingleton::get() is creating a new instance, something it shouldn't do of course.
