The Kardashians are finally back this Sunday night for season 11 of their popular reality series that made them household names. The new season will follow one of the world's most famous families throughout this past summer, which was a very eventful one for the Kardashian clan. The new season will include episodes about Kourtney Kardashian and Scott Disick's breakup, Kylie Jenner's extravagant 18th birthday party, Khloe's Complex cover shoot, Caitlyn Jenner's acceptance of the Arthur Ashe Courage Award at the ESPY's, and more! Check out everything there is to look forward to when "Keeping up with the Kardashians" returns this Sunday.

Khloé Kardashian's sexy Complex photo shoot

Over the Summer, Khloé showed off her amazing new body on the August cover of Complex Magazine. While she did look great in the pictures, it seems as though she needed some convincing to actually go through with shooting it. The 31-year-old reality star is currently in the best shape of her life and has lost about 35 pounds through a tough workout regime, as HNGN previously reported.

In a preview of the upcoming season, Khloé tells her sister, Kim Kardashian, that people kept on telling her how "fat" she used to look in pictures.

"If you just do so many photo shoots, it will replace all the bad ones," Kim advised her little sister. "What do you want out there on the Internet? Don't you want to replace every bad image of you?"

"These people have the best bodies," she said. "I can't do that."

In the end, Khloé did get enough courage to do the photo shoot and looked great!

Kylie Jenner Turns 18

The youngest member of the Kardashian/Jenner family, Kylie, turned 18 this past August and threw herself one luxurious birthday bash. To celebrate her turning the legal age, the teenager partied at West Hollywood nightclub Bootsy Bellows. The birthday party was invite-only and saw performances by her boyfriend, Tyga, and Fetty Wap.

The most eventful part of the evening was when the rapper gifted his newly legal girlfriend with a brand new Ferrari, as HNGN previously reported. The 25-year-old decorated the luxury car with a giant red bow as he completely shocked Kylie. The car, a white Ferrari 482 Italia, is reportedly worth $320,000.

Days later, Kylie continued to celebrate her birthday in Montreal. The celebration happened at the Beachclub Montreal, a mini party island with its own beach, pool, lots of A-list DJs, and of course, a ton of booze, with the drinking age in Canada being 18. She was supposedly paid between $100,000 and $200,000 for her own party.

Caitlyn Jenner receives the Arthur Ashe Courage Award at the 2015 ESPYs

Caitlyn Jenner, formerly known as Bruce Jenner, was awarded the Arthur Ashe Courage Award at last summer's ESPY awards, as HNGN previously reported. The event was attended by all of Caitlyn's children, as well as all of her step-children, expect Rob Kardashian. The 65-year-old former Olympian gave an emotional speech at the ceremony where she shared her journey to becoming a transgender woman, the issues that trans people face, and of course, her famous family.

In a sneak peak at the upcoming season 11, Caitlyn's youngest children, Kendall and Kylie, get into a huge fight over a dress right before the ceremony. In the clip from E!, tensions are high as the two get ready for their father's big night because Kylie would not let her older sister borrow her "favorite dress."

"She can't wear that," Kylie tells her assistant. "So just take it out of her bag."

The two then get into a heated argument where Kendall called Kylie "literally the biggest f--king bitch I've ever met."

"Uh, touché," Kylie responded.

Kourtney Kardashian ends her relationship with Scott Disick

Perhaps the most eventful thing that happened over this past summer to the Kardashian family was when Kourtney broke up with her longtime boyfriend, Scott. The couple was together for nine years and have three children together.

Everything fell apart when the 32-year-old partier was photographed getting cozy with his ex-girlfriend Chloe Bartoli in the South of France, as HNGN previously reported. Kourtney and Scott's rocky relationship and his erratic alcohol and drug-fueled behavior have been well documented throughout the "Keeping up with the Kardashians" series.

A preview for the upcoming season features a scene in which Scott is carrying boxes out of the home he shared with Kourtney and their children, 5-year-old Mason, 3-year-old Penelope and 10-month-old Reign. Emotions are high as the troubled father sits down with Kris, Khloé, Kim and Kourtney, in which all parties are seen crying. Kris tells Scott that it breaks her heart to see her daughter in pain while Scott admits that "he f----d up" and "made the worst decision" he could have ever made in his life.

"It's been a really hard time going from having all of you guys to having nobody," Scott tells his ex and her family.

In another sneak peak of season 11, Kourtney seems to have moved past her tears and tells her mother and Kim about the status of Scott.

"Is Scott okay?" Kris asks.

"I don't know," Kourtney responds. "I mean, this is what he wants to be doing, so there's nothing I can do at this point. That's life."

Kris then tells Kourtney that she is doing the right thing and that it is "time to move on and find your happiness."

"I don't care about anybody," Kourtney replies. "I just want to care for my kids."

Other eventful things sure to be seen this season on "Keeping up with the Kardashians" include the first family dinner with Caitlyn, Khloé ex Lamar Odom and current flame James Harden running into each other in Las Vegas, and the girls trip to St. Barts.

"Keeping Up With the Kardashians" season 11 premieres Sunday, Nov. 15 at 9 p.m on E!.
