The cult-favorite reality show show Big Brother has been around for nineteen seasons, making contestants live together under constant surveillance, cutting connection from anyone who is not also living in the house, and ending each week with a voted-on eviction for an eventual cash grand prize.

To add a twist little twist after nearly 20 seasons, this year marks the first time the stateside version of the show will feature an all-celebrity cast for the appropriately named Celebrity Big Brother. The season -- which kicked off Feb. 7 -- began with 11 lucky (or perhaps unlucky) guests, each coming equipped with their own celebrity ego. And while they each gained fame and/or notoriety in their day, it's understandable if it's maybe a little hard to place exactly where that familiar face came from. So we've broken down the career of each cast member, giving you a quick glimpse into their resume before they entered the house.

Ariadna Gutierrez

In 2015, Steve Harvey incorrectly announced the winner of the Miss Universe pageant, leading to an awkward and very literal un-crowning, as well as one of the all-time most memed moments in pop culture history. Ariadna Gutiérrez was the Miss Columbian queen at the unfortunate end of the infamous debacle, finishing as first runner-up in the competition, only moments after thinking she had clinched the top spot.

Brandi Glanville

Celebrity Big Brother will certainly not be the first time Glanville graces a reality television show screen. In fact, reality TV is exactly why she’s on the celebrity edition of the show. The New York Times best-selling author (her 2013 book is entitled Drinking and Tweeting) originally gained her fame on Bravo's The Real Housewives of Beverly Hills, where she starred on the show from seasons two through, through 2011 to 2015. Since then, she’s racked appearances on Celebrity ApprenticeFamously Single, and My Kitchen Rules.

Chuck Liddell

Chuck Liddell is a world-famous mixed martial arts fighter, whose accolades include a UFC light heavyweight championships in 2005 and 2006, and an induction into the UFC Hall of Fame in 2009. Though he's since retired, he's filled his time with a lengthy run on Dancing With the Stars in 2009.

James Maslow

James Maslow might resonate more with fans of the show who are somewhere in the mid-twenties age range. The singer originally starred as one of the cast members of the Nickelodeon show Big Time Rush, a series about a boy band, whose cast members made a boy band in real life. After the end of the show, and the group’s inevitable split, Maslow gained attention again doing covers on his YouTube channel, garnering millions of views and earning himself a performance spot at last year's iHeartRadio Music Festival as the Macy's Rising Star contest winner.  

Keshia Knight Pulliam

​Pulliam is all grown up. If the now 38-year-old former child star seems familiar, it's likely thanks to her role as Rudy Huxtable on the famed Cosby Show, which she played for eight years. She went on to also star in Tyler Perry's House of Payne from 2007 to 2012.

Marissa Jaret Winokur

Playing Tracy Turnblad in the Tony award-winning show Hairspray, Winokur is objectively one of the most famous Broadway stars. Much like some of the other cast members, she has also starred on a season of Dancing With the Stars before hitting the Celebrity Big Brother house.

Mark McGrath

Mark McGrath looks exactly as you probably remember. As the lead singer of Sugar Ray, he gained fame in the late 90's for songs like "Fly" and "When It's Over" and then continued his career after the band's split as the one of the hosts of the celebrity gossip show Extra from 2004 to 2008.

Metta World Peace

Metta World Peace may be better known as his former (birth) name Ron Artest to fans who haven't been paying attention for the last decade or so. The former NBA player was one of the league's biggest defensive forces throughout the early 2000's, earning him defensive player of the year in 2004, and being a key player in winning a championship for the Los Angeles Lakers in 2010. Potentially more notable than his defense, though, World Peace is widely remembered for taking part in most of the on court fights that happened during his time in the league, including the infamous Malice at the Palace, a fight that involved both fans and players.


Omarosa is the reality star villain-turned-White-House-staffer, who has already dropped insider info on her tumultuous relationship with Donald Trump on this season's show. She originally met the president on his own reality show The Apprentice, competing in the show in 2004, and then coming back again for subsequent seasons of Celebrity Apprentice. Fast forward to 2017, and she is hired (and then quickly fired) as the Director of Communications for the Office of Public Liaison for the Trump administration.

Ross Mathews

In simper times, Ross Mathews was simply known as "Ross the Intern," as a correspondent and an actual intern on The Tonight Show with Jay Leno. Since then, he's hosted and starred in a plethora of shows, often all at the same time, including judging on RuPaul's Drag Race, interviewing on the red carpet for E!, and competing on Celebrity Fit Club.

Shannon Elizabeth

Shannon Elizabeth was a go-to for campy blockbuster movies in the late nineties and early 2000's, starring in the original and sequel of American Pie, as well as Scary Movie. You may also recognize her from her television appearances, as she's starred in That '70s ShowCuts, and various roles since.
