This post was part of the AOL Money & Finance Best & Worst of 2007 feature. The voting has now closed and readers have chosen Rosie O'Donnell's war of words with Donald Trump and others as the dumbest celebrity feud of the year. Be sure and let us know in the comments if you are pleased with this result.

Back in the day of the (fictional) Capulets and Montegues or the (real) Hatfields and McCoys, "feuds" were not something to be taken lightly. They separated men from boys and resulted in certain bloodshed. These days, tabloids will report on a new "celebrity feud" each week, as our nation's most rich and famous lash out at one another in the press or on live television.

Sometimes, there are justified reasons for unrest among pop culture's elite ... a cuckolding, perhaps, or a vicious custody battle (I blame Alec Baldwin's recent poor judgment on stress, but maybe he gets off lightly in my book because he's so brilliant on 30 Rock). At any rate, here's some of the most high-profile fights that took center stage in 2007.

The American public twice served as judge and jury for Rosie O'Donnell this year. Late last year, the comedienne found herself in a war of words with "The Donald" (Trump), after O'Donnell criticized the billionaire's handling of a scandal involving the Miss USA Pageant, of which Trump holds the rights. Name-calling and mudslinging ensued, and O'Donnell colleague Barbara Walters caught some shrapnel. Months later, on the May 23 episode of The View -- on which the liberally minded Rosie served as one of four co-hosts -- she got into a heated (split-screen!) debate with Elisabeth Hasselbeck, the "conservative" member of the hosting panel. Tempers flared and Rosie ultimately walked out on her contract with the program, which was set to expire a few months later anyway. Whoopi Goldberg and Sherri Shepherd have since picked up hosting duties.
