Keeping Up with the Kardashians
With all of the recent transformations, pregnancies, new kids and step-siblings joining the mix, it can be complicated keeping up with the Kardashians (and Jenners).
There are four Kardashian siblings (Kourtney, Kim, Khloe and Rob), from momager Kris Jenner's first marriage to Robert Kardashian. There are two Jenner girls, from the marriage between Kris and Bruce Jenner (Kendall and Kylie). Bruce, now Caitlyn Jenner, has three sons and a daughter from previous marriages (Burt, Casey, Brandon and Brody). And on top of that, the Kardashian and Jenner "kids" have now started getting married and having kids of their own.
Confused? It's easy to be. So, let's break down reality TV's royal family, member by member.

This is Caitlyn Jenner (formerly Bruce).
The world got its first glimpse of the iconic athlete's new look on June 1, 2015, when Vanity Fair released a photo of its July cover, featuring an exclusive Annie Leibovitz portrait of the star.
Caitlyn's family members and celebrity supporters, then quickly took to social media to voice their admiration for her brave and groundbreaking transition.

Breaking world records again
Shortly after Vanity Fair released its July Cover, introducing the world to Caitlyn Jenner, the Olympian broke yet another world record.
Caitlyn Jenner (formerly Bruce Jenner) is now the fastest Twitter user in history to reach 1 million followers. Passing the social media milestone in just 4 hours (she now has even more), the gold medal decathlon winner surpassed even President Obama, who previously held the record.
The other Kardashian in the news right now is the family's arguably most famous member in current pop culture, Kim.
Kim Kardashian propelled her family into the spotlight in 2007, when a sex tape she filmed with former boyfriend Ray J in 2003, was leaked online. E! then signed her family to a reality show, called "Keeping Up with the Kardashians," which has now been on the air for 10 seasons.
Here, the social media queen signs copies of her new compilation of selfies, "Kim Kardashian West: Selfish," at Barnes & Noble, 5th Avenue in New York City, May 5, 2015.

Kris Jenner, seen her at the 2015 NBC Universal Cable Entertainment Upfronts, is the often polarizing matriarch of the Kardashian/Jenner clan.
A mother of six, stepmother of four (five, if you include Brandon's wife, Leah), and grandmother of four -- Kris Jenner is also a television host and a fierce publicist.

Kourtney Kardashian is the first and oldest of the Kardashian siblings. Her parents are Kris Jenner and Robert Kardashian, a lawyer who famously defended O.J. Simpson in the mid-90s and lost his battle with esophageal cancer at the age of 59.

The third and youngest of the frequently photographed Kardashian sisters, who resulted from Kris Jenner's first marriage to Robert Kardashian, is Khloe.
Known for her snarky sense of humor and take no prisoners attitude, Khloe Kardashian is a favorite among many fans.

Khloe Kardashian married NBA player Lamar Odom in 2009, and the couple had their own spinoff show, "Khloe & Lamar," on E! for two seasons.
However, the marriage unraveled after Lamar lost his spot on the Los Angeles Lakers' roster and consequently succumbed to a very public drug addiction.

Rob Kardashian (or, more formally, Robert Kardashian Jr.) is the yougest of the four core Kardashian siblings.
Seen here, during his time on ABC's "Dancing With The Stars," Rob is no longer a regular on the family's reality show, due to his ongoing struggles with his weight.

Kylie Jenner is the younger of Kris and Caitlyn (formerly, Bruce) Jenner's two daughters.
Arguably the edgiest of the Kardashian/Jenner siblings, Kylie has amassed a huge social media following. She has also been in the news a lot for her changing appearance. Before admitting to having filler professionally injected into her lips, teens across the world tried to mimic her lush lips "naturally," by using the suction from small cups. The so called #KylieJennerChallenge was extremely dangerous and led to facial damage, for some, which cannot be remedied.
Here, she attends DuJour Magazine's event, celebrating her Bruce Weber photo shoot with sister, Kendall, August 28, 2014.

Caitlyn Jenner (formerly, Bruce Jenner) also has two sons with her ex-wife Linda Thompson. The younger of those boys, Brody Jenner, was a reality television personality in his own right... even before "Keeping Up with the Kardashians" became a thing.
Brody, seemingly always featured as a hard to pin down heartthrob, has starred on "The Princes of Malibu"(2005), "The Hills"(2006) and "Bromance"(2009), in addition to his appearances on "Keeping Up with the Kardashians."

Brandon Jenner is married to Leah Jenner, and the two of them are a welcome zen presence, whenever they appear on the family's reality show. Leah, like her husband, is a professional musician and singer.
And as it's readily apparent in this picture, posted to mother-in-law Linda Thompson's Instagram feed, the couple is now expecting their first child.
