Tensions between American Idol stars Ryan Seacrest and Simon Cowell are coming to a head. Here is a timeline detailing their past friction:

1984: Cowell hangs up on a 10-year-old Seacrest following bitter dispute over whether Mocha Sugarcreek should have won Best Vocal Group on Star Search

2002: Producers tell Seacrest and Cowell that the show will be more entertaining if there is conflict between them

2003: In his book I Don't Mean To Be Rude, But…, Cowell refers to Seacrest throughout as "Bryan"

2004: Cowell quietly repeats everything Seacrest says for entire broadcast

2005: During a production meeting, Seacrest eats a cranberry Danish that Cowell had his eye on

2006: Names on the stars' dressing rooms are mysteriously changed to "Bowell" and "Peecrest"

2007: Paula Abdul says some inane bullshit about singing, and Seacrest goes to commercial before Cowell can respond with some equally inane bullshit
