How do I unnest a column in a pandas DataFrame?

I have the following DataFrame where one of the columns is an object (list type cell):

df=pd.DataFrame({'A':[1,2],'B':[[1,2],[1,2]]})
df
Out[458]: 
   A       B
0  1  [1, 2]
1  2  [1, 2]

My expected output is:

   A  B
0  1  1
1  1  2
3  2  1
4  2  2

What should I do to achieve this?
