There was a lot of love this year thanks to some of our favorite couples of 2011 , but there was also some heartache. And some of the biggest splits of the year made some of the biggest headlines. As the year comes to a close, MTV News reflects on some of the buzziest breakups of the past 12 months.

Jennifer Lopez and Marc Anthony
In July, the “American Idol” judge and her “Papi” called it quits after two kids and seven years of marriage . Despite the split, the two seem to remain on good terms, being spotted together shooting their reality show, “Q’Viva.” Lopez referenced their ability to work together when she spoke to Vanity Fair , sharing, “We actually work great together, and he was always very supportive. … He will always be in our lives.”

Ashton Kutcher and Demi Moore
The rumors had been floating around for some time that there was trouble in their marriage, and the couple finally fessed up to their plans to divorce in November. “Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light,” the former “Punk’d” star tweeted about the end to his six-year marriage from the Hollywood A-lister.

Ashlee Simpson and Pete Wentz
Days before Valentine’s Day, Ashlee and Pete confirmed they were divorcing . Over the course of their three-year marriage , the two fended off rumors of marital woes and had frequently been spotted side by side supporting one another. Eventually, the pair split over “irreconcilable differences.” They have a son, Bronx.

Ben Gibbard and Zooey Deschanel
They were every indie fan’s dream couple, but in November, Gibbard and Deschanel announced they would no longer be singing the same tune. Married only two years, sources close to the couple described the split as “mutual and amicable.”

Kim Kardashian and Kris Humphries
This became the mother of all celeb splits in the past 12 months. Sure, the wedding was news, but the breakup , after only 72 days of marriage, was even more buzzed about. Since the October 31 announcement, the reality starlet and her former basketball-playing hubby have continued to make headlines (and more headlines and more headlines) thanks to “Kourtney & Kim Take New York,” which seems to document the demise of their relationship.
