Most millennials grew up during the early ages of reality TV. I'm talking VH1's "Flavor of Love" with rapper Flavor Flav, MTV's "The Real World" and ABC's "The Bachelor", you know, the classics. One thing about reality shows, though, is that they come and go. And, sometimes, in this case, make a comeback. MTV's hit series "The Hills" will be back this summer with a new(ish) title, "The Hills: New Beginnings".

The show originally was a spin-off of MTV's "Laguna Beach" and followed lead Lauren Conrad to Los Angeles where she mingled and attended school. The series' first run last six seasons before the final episode aired on July 13, 2010. 

We still have a few weeks before the reboot catches us up on the lives of our favorite stars, so, to kill some time, let's take a look back to see what we missed from some current and former castmates, as well as get to know the newbies. 

Lauren Conrad ("L.C."): Now known as Lauren Tell, the star of "Laguna Beach" and its spinoff "The Hills", seems to be enjoying life out of the limelight. After leaving the series in 2009, "L.C." continued her fashion career path collaborating with notable stores such as Kohls and Nordstrom for collections. She has also released several books landing her on The New York Times Best Seller List. The former "Hills" star married former Something Corporate guitarist William Tell in 2014. The two share a son born in July 2017 and are currently expecting baby No.2. Unfortunately for fans, Conrad will not be returning for the show's reboot but can keep up with her on her podcast "Lauren Conrad: Asking For A Friend".

Kristen Cavallari: Notoriously cast as the mean girl, fans will remember that Kristen was a cast member on "Laguna Beach" alongside Conrad. Although Cavallari was not initially cast on "The Hills", she did take over the lead role once Conrad left the series midway through season five. Currently, Cavallari is married to former Chicago Bears quarterback Jay Cutler. The two reside in Nashville and share three children together. Cavallari will not be joining the new series but she'll still be keeping busy running her rapidly growing fashion and lifestyle brand Uncommon James and filming her show "Very Cavallari" which was just picked up by E! for its third season.

Heidi Montag and Spencer Pratt ("Speidi"): Both Heidi and Spencer will both be returning to the hit series. The outcasted couple continued on reality tv even after "The Hills" ended appearing on "Marriage Boot Camp" and twice on "Celebrity Big Brother UK". The two host the podcast "Make Speidi Famous Again" and sell crystals curated by Spencer. Montag gave birth to their son, Gunner Stone, in 2017. 

Audrina Patridge: One of the first friends L.C. made in Los Angeles will be coming back to the series. Since "The Hills" ended, Patridge had a short-lived marriage (two years) and gave birth to her daughter Kirra Max in 2016. She pursued an acting career, receiving some small roles before becoming the host of NBC's travel series "1st Look" in 2014 and 2015.  

Brody Jenner: Originally appearing as quite the playboy, Jenner has since settled down and married Kaitlynn Carter in 2018. After "The Hills", Jenner went on to appear in his own spin-off dating show on MTV called "Bromance", which lasted only one season. Fans will be excited to know this stud will be returning to television screens in June. 

Whitney Port: Who could forget Conrad's Teen Vogue bestie? Whitney appeared in the first four seasons of "The Hills" before moving the New York City and starring in the spin-off "The City" which followed her career and personal life in the new city. "The City" last aired in July 2010. She then, Whitney married Tim Rosenman in 2015 and the two welcomed a baby boy in 2017. Port will be appearing in "The Hills: New Beginnings".

Also, confirmed to appear are Stephanie Pratt (Spencer Pratt's sister), Jason Wahler (Lauren Conrad's ex-boyfriend -- the one she skipped Paris to be with), Justin "Bobby" Brescia (who Audrina had an on-again-off-again relationship) and Frankie Delgado (Brody Jenner's friend).

Along with the OG's, the show will introduce five new cast members including actress Mischa Barton and Brandon Thomas Lee, who is the son of Tommy Lee and Pamela Anderson.

MTV's "The Hills: New Beginnings" is set to air on June 24 on MTV.
