Marriage is supposed to be one of the most sacred steps in a couple's romantic life.

Committing to a lifetime of married bliss together is an adventure that most couples do hope to embark on at some point in their lives. Several do take that step in fact, and some manage to make it work for the rest of their lives. Unfortunately, that isn't the case with all marriages.

The divorce rate is nearly 50 percent these days, which can be a daunting figure to those who do wish to tie the knot one day. Sadly, the rate can swallow up couples from any walk of life-including celebrities. Several announce sad and shocking splits each year.

With that in mind, Enstars compiled a list of eight couples who announced shocking plans to divorce or separate in 2013:

1. Kris & Bruce Jenner: The matriarch and patriarch of the famous Kardashian/Jenner clan announced they were separating after 22 years of marriage in October, though they had reportedly been living apart since June. The couple were the heads of the famous family that includes Kris's children from her first marriage to the late Robert Kardashian: Rob, Kim, Khloe and Kourtney. Bruce is the father to Brody and Brandon Jenner. Together Bruce and Kris have daughters Kendall and Kylie. Despite the news that they were separated they have by being spotted out together several times since the announcement was made.

2. Michael Douglas and Catherine Zeta-Jones: Though they managed to prove age was just a number, Douglas and Zeta-Jones, who are 25 years apart in age, announced their split after 13 years of marriage in August. During their time as a married couple they survived a stalker who threatened to kill Catherine if she didn't leave Michael and his bout with throat cancer. However, the two don't appear to be rushing into a divorce anytime soon either. Both have since been spotted still wearing their wedding rings and Douglas has still referred to her as his "wife" on several occasions, for example during his acceptance speech at the 2013 Emmy Awards.

3. Diane Lane and Josh Brolin: Lane and Brolin announced they were parting ways back in February after eight years of marriage. According to court records, Lane filed a petition for divorce from her second husband the day after Valentine's Day. She cited irreconcilable differences as the reason for the split.

4. Courtney Stodden and Doug Hutchison: The two made headlines two years ago when Hutchison, then 51, married Stodden, who was only 16 at the time. They announced their split at the end of October. Stodden has reportedly said since that she found marriage "strange."

5. Jane Lynch and Dr. Lara Embry: The Glee actress filed for divorce from her wife in July after three years of marriage. The couple has reportedly kept the proceeding drama-free, though Embry did ask for a reported $93,809 a month in spousal support back in September.

6. Orlando Bloom and Miranda Kerr: Another couple to announce their split in October after a three-year marriage and six-year relationship. The actor and former Victoria's Secret model, who had son Flynn in 2011, have been the models of amicable splits.

7. Clint and Dina Eastwood: After a 17-year union, the Eastwood's began formal divorce proceedings in October, when Dina filed papers based on irreconcilable differences. She reportedly is seeking spousal support from the actor and director, as well as full physical custody of their 16-year-old daughter Morgan.

8. Ashley Judd and Dario Franchitti: The actress and racecar driver announced their plans to separate back in January but after Dario was involved in a serious accident at the Houston Grand Prix in early October, Judd rushed to the hospital to be by his side. Since then, the couple has announced that they will be giving their marriage another try after Franchitti recovers.
