MARRIED 2 YEARS
TROUBLE IN PARADISE: After months of rumors that she was through with her rapping hubby, Spears made it official on Nov. 7, filing for divorce in L.A.
AFTERMATH: On Dec. 7 Brit defended her partying with new BFF Paris Hilton: "It's been so long since I've been out on the town with friends;" Fed-Ex said in an interview that he's doing "great." The pair have yet to hash out custody of sons Sean Preston, 1, and Jayden James, 3 months.
Paul McCartney & Heather Mills McCartney
MARRIED 3+ YEARS
TROUBLE IN PARADISE: They announced their split on May 17.
AFTERMATH: All you need is love? Hardly. After they separated, tales of Mills McCartney's past appeared in British tabs, alleging she was once a call girl (she denied it); 18-year-old nude photos of the land-mine activist also surfaced. McCartney got bad press as well—a draft of Mills McCartney's divorce petition, in which she claimed he was abusive to her, was leaked to the media, along with reports that she had audiotapes of him berating her. The futures of daughter Beatrice, 3, and Sir Paul's estimated $1.5 billion fortune (oops, no pre-nup) have yet to be decided. Meanwhile Mills McCartney has acted as her own attorney in some early hearings, and the former Beatle says he's seeing a shrink.

TROUBLE IN PARADISE Days before Locklear (who has a daughter, Ava, 9, with Sambora) filed for divorce on Feb. 3, she allegedly found provocative photos e-mailed to the Bon Jovi guitarist by a woman they both knew.

MARRIED 7 YEARS
TROUBLE IN PARADISE: The pair, who have two kids, Ava, 7, and Deacon, 3, sparked talk of a split when they bickered at an Oct. 16 party; two weeks later, they split.
AFTERMATH: Phillippe defended himself amid reports linking him to actress Abbie Cornish, 24: "I'm not a perfect person, but I'm not guilty of a lot of the things I have been accused of." In any case, Witherspoon is keeping busy—she's now filming the political thriller Rendition in Los Angeles.

The couple have feuded over $274,000 Evans says Schelske took from their bank account; custody of the kids is not yet decided.
Jennifer Aniston & Vince Vaughn
DATED 14 MONTHS
TROUBLE IN PARADISE: They started a relationship while filming The Breakup, but the pair had spent only a few days together after Vaughn left to film Fred Claus in England this September. Despite tabloid rumors that they had split months ago, the couple told PEOPLE that they parted ways in late October—after Aniston visited Vaughn in London.
AFTERMATH: With a breakup as low-key as their romance, there has been little drama: "They continue to be good friends today," say their reps. Aniston is back in L.A.; Vaughn's movie wraps later this month.
