Apparently, these celebs didn't get the memo. The slideshow below showcases some of the harshest names stars have called their exes -- from an actor who wrote toxic tweets about his ex-wife, to another celeb who didn't mince words when describing what his ex was like in the sack.
Which star called her soon-to-be ex-husband a "pig" on national television?
<strong>a) Demi Moore b) Jennifer Lopez c) Kim Kardashian d) Maria Shriver </strong>
Since <a href="http://www.huffingtonpost.com/2011/07/15/jennifer-lopez-marc-anthony-divorce_n_900394.html" target="_hplink">announcing their split in July 2011</a>, Jennifer Lopez and Marc Anthony have played nice as judges on <a href="http://www.huffingtonpost.com/2012/01/20/jennifer-lopez-marc-anthony-divorce_n_1219568.html" target="_hplink">"Q'Viva! The Chosen," the reality show they co-produce</a>. Most of the time, anyway. In the scene above, Lopez gets a little peeved when Anthony calls a few female contestants his "babies" during auditions. <a href="http://on.aol.com/video/jennifer-lopez-calls-marc-anthony-a-pig-517326594" target="_hplink">"You're a pig," Lopez tells Anthony with a glare,</a> as he awkwardly stares at the camera. (Luckily for him, Lopez quickly breaks the tension in the room with a playful laugh.)
Which ex-husband said sleeping with his superstar wife was like "cuddling up with a piece of gristle"?
<strong>a) Billy Bob Thornton b) Ashton Kutcher c) Guy Ritchie d) Kelsey Grammer </strong>
ANSWER: Guy Ritchie
The tabloids had a field day when <a href="http://www.people.com/people/article/0,,20233183,00.html" target="_hplink">Madonna filed to divorce Guy Ritchie</a> in October 2008 and details slowly eked out about the couple's failed eight-year marriage -- including their sex life. In an issue of <em>Us Weekly,</em> a source claimed that Ritchie compared going to bed with Madonna to <a href="http://gawker.com/5067040/messy-divorces-old-wrinkled-madonna-vs-sneaky-coward-guy-ritchie" target="_hplink">"cuddling up with a piece of gristle."</a> But hey, the marriage wasn't all it was cracked up to be for Madonna, either. In August 2009, the Material Girl told <em>Rolling Stone </em>that she was glad she could concentrate on her work during her "challenging" marriage because otherwise, she "<a href="http://www.huffingtonpost.com/2012/01/31/madonna_n_1244961.html" target="_hplink">may have thrown [herself] off a building."</a>
QUESTION: Who called her ex-husband a "lazy ass" on "The Late Show"?
<strong>a) Jennifer Aniston b) Anne Heche c) Kate Hudson d) Britney Spears </strong>
ANSWER: Anne Heche
David Letterman likely got more than he bargained for when he asked actress Anne Heche about her ex-husband, Coley Laffoon, in August 2009. "Can you say 'lazy ass' on TV?"<a href="http://www.x17online.com/celebrities/anne_heche/anne_heche_disses_her_exhusband_calls_him_a.php" target="_hplink"> Heche said of her ex</a>, who was awarded a <a href="http://www.accesshollywood.com/anne-heche-to-pay-ex-275000-in-divorce-settlement_article_9834" target="_hplink">$275,000 settlement in the couple's 2008 divorce</a>, along with $3,700 per month in child support for the couple's son, Homer. <a href="http://www.x17online.com/celebrities/anne_heche/anne_heche_disses_her_exhusband_calls_him_a.php" target="_hplink">When Letterman asked what Laffon did for a living</a>, Heche had even more to say: "He goes out to the mailbox and he opens up the little mailbox door and goes, 'Oh! I got a check from Anne! Oh! I got a check from Anne! Yay!'"
Which actor called his ex a "vile kidnapper" and a "dog thief"?
a) Mel Gibson b) Charlie Sheen c) David Hasselhoff d) Alec Baldwin

"We must bombard with Warlock Napalm, that traitor and loser whore #DUH-neese POOR-ards. a vile kidnapper and now dog thief. hate," <a href="http://www.popeater.com/2011/03/28/charlie-sheen-denise-richards/" target="_hplink">Sheen tweeted to some 3 million followers</a>.
QUESTION: Which ex-husband called his more famous ex-wife a "narcissistic egomaniac" and a "second-rate celebrity"?
<strong>a) Jesse James b) Tony Parker c) Peter Cook d) Kris Humphries </strong>
ANSWER: Peter Cook
Four years after the divorce, Peter Cook <a href="http://www.huffingtonpost.com/2012/03/07/christie-brinkley-divorce_n_1327425.html" target="_hplink">still had a few choice words to describe</a> ex-wife Christie Brinkley. The Hamptons architect called Brinkley a "<a href="http://www.dailymail.co.uk/news/article-2108986/Christie-Brinkleys-ex-calls-narcissistic-egomaniac-explosive-91-page-court-filing.html#ixzz1nyt9tBDe" target="_hplink">narcissistic egomaniac</a>" in court docs filed during their recent custody battle, later calling the model a "<a href="http://www.huffingtonpost.com/2012/03/06/christie-brinkley-a-second-rate-celebrity_n_1324269.html" target="_hplink">second-rate celebrity starved for attention</a>." The pair <a href="http://www.huffingtonpost.com/2012/06/25/christie-brinkley-and-peter-cook_n_1625861.html" target="_hplink">settled the custody dispute out of court in June,</a> and so far, it's been all quiet on the name-calling front.
Who reportedly called her ex a "rich bully"?
<strong>a) Ellen Barkin b) Oksana Grigorieva c) Heather Mills d) Elin Nordegren</strong>
ANSWER: Oksana Grigorieva
In the midst of her <a href="http://www.people.com/people/article/0,,20402847,00.html" target="_hplink">custody battle with Mel Gibson</a>, Oksana Grigorieva reportedly <a href="http://articles.nydailynews.com/2010-10-18/gossip/27078575_1_lawyers-law-firms-oksana-grigorieva" target="_hplink">called the actor a "rich bully"</a> who had punched her in the face and threatened to kill her. (Released tapes of the <a href="http://www.huffingtonpost.com/2010/07/12/mel-gibson-second-audio-t_n_643100.html" target="_hplink">actor ranting and cursing at Grigorieva</a> probably didn't help his case.) In August 2011, a judge granted the couple joint custody and ordered <a href="http://www.huffingtonpost.com/2011/08/31/mel-gibson-to-pay-ex-750k_n_943566.html" target="_hplink">Gibson to pay $750,000 to Grigorieva</a> and to continue to provide housing and financial support for their daughter.
