Not unlike other recent years, 2010 brought big business to some of Hollywood’s (and other locations’) highest profile divorce attorneys. We’ve covered many of this year’s most publicized celebrity divorces and separations here on this blog over the last 12 months.

Something about putting them all on one page in list format makes the sheer volume of celebrity splits a bit staggering. Take a look:

• Tamra Barney and Simon Barney – After watching this pair on The Real Housewives of Orange County, we can’t say we were surprised at this split.

• Dennis Hopper and Victoria Hopper – He filed for divorce while dying of cancer. The fight quickly became public and bitter. He eventually passed away before the divorce could be finalized. She continued litigating against his estate.

• Noah Wyle and Tracy Wyle – The ER actor announced his separation from his wife of 11 years at the beginning of 2010.

• John Edwards and Elizabeth Edwards – The former politician and his wife separated at about the same time that he finally admitted paternity of his mistress’s child. He had previously denied fathering the little girl. Elizabeth Edwards died of cancer later in the year, before any divorce was finalized.

• Allen Iverson and Tawanna Iverson – AI’s longtime wife filed for divorce just as the NBA star stepped away from the game to be with his family because of a child’s illness. The couple was together for over 15 years, married for over eight.

• Sandra Bullock and Jesse James – These two split in the spring shortly after Bullock won an Academy Award. Bullock discovered that James cheated on her repeatedly with at least one, if not several, women over the course of their marriage. She was still able to complete the adoption of a baby boy, despite the divorce.

• Eva Longoria and Tony Parker – Each filed for divorce this fall, amidst rumors that Parker cheated on Longoria (or, at least, was involved in an inappropriate emotional relationship) with an ex-teammate’s wife.
