No, Lady Gaga and Rihanna are not dating.
lady gaga why??
LADY GAGA, any day!
probably rihanna because she has sung longer than lady gaga.
What?
Lady Gaga definitely. She has more followers than Rihanna.
That's a matter of opinion, but recently Rihanna has been thought to be 'copying' lady gaga so I suppose you could say the majority of people would think Lady Gaga was better than Rihanna though Rihanna has been in the music industry before Lady Gaga was known, it depends on what you think makes an artist 'better' than others. Lady GAGA!
