A source tells the Star, “Christina is threatened by any successfulwoman, but Gaga really gets under her skin. Christina’s fragrance line is her
baby, and she’s extremely territorial – especially since her album sales have tanked. When Gaga first arrived on the scene, Christina predicted she’d be a one-hit wonder. It drives her crazy that she was so wrong. Christina can be
really low-class and has been saying she wants to kick Gaga’s ass! They could easily end up at the same party, especially with the holidays coming up. Things could really get out of hand.”
