'Celebrity Big Brother' Spoilers: Full Cast List Leaks -- See Which 10 Celebs Will Be On 'CBB US'

Belynda Gates Turner

Celebrity Big Brother spoilers have broken loose! The entire cast of 10 leaked today on social media in advance of the official CBS announcement slated to happen during this Sunday's Grammy Awards. In the latest CBB US promo, host Julie Chen promised that the cast would include actors to athletes and everything in between. With this cast reveal, it looks like there is more of the "everything in between" than actors or athletes. Here is a look at the houseguests for the first-ever Big Brother: Celebrity Edition.

Sammi Giancola

As Inquisitr leaked a while back, Sammi "Sweetheart" Giancola, formerly of Jersey Shore, is one of six reality stars in the CBB US cast. As was reported, Sammi opted out of MTV's Jersey Shore Family Vacation special to participate in Big Brother (and also to avoid her ex, Ronnie).

Johnny Bananas

This guy is an MTV staple who has appeared in multiple seasons of The Challenge. In fact, Johnny is on the Vendettas season airing currently where he's competing alongside BB alumnus Natalie Negrotti and Victor Arroyo. From recent footage, it seems Johnny and Natalie might be showmancing.

Beth Chapman is the better half of Dog The Bounty Hunter. Beth was recently declared cancer-free after a battle with stage two throat cancer. Beth and her husband Duane Chapman (aka Dog) had an A&E show that aired for nine years, and she's also guested as herself on Hawaii 5-0.

Brody Jenner

The other celeb houseguests might have a lot of questions for Brody Jenner about his more famous family members, but he's accustomed to the limelight. Brody did a number of episodes of Keeping Up With the Kardashian with his step-sisters as well as three years in front of reality cameras on The Hills.

Tiffany Pollard

Tiffany Pollard is known for Flavor of Love where she gained the nickname "New York," but she parlayed her 15 minutes of fame into more. She landed three reality shows of her own and was a houseguest on UK's Celebrity Big Brother where she placed fourth, lasting 32 days in the house.

Andrea Boehlke is the only CBS reality alumnus among the CBB US houseguests. Andrea was on three seasons of Survivor with her best finish at fifth place. Her longest stay was 37 days, so it seems like the short and starvation-free run of Big Brother: Celebrity Edition should be no hardship.

Matt Iseman

Dr. Matt Iseman is a physician-turned-comedian and TV host known for American Ninja Warrior, Clean House, Messiest Home, Comics Unleashed, and Hallmark's Home & Family. Iseman's only reality TV contestant experience was last year's new Celebrity Apprentice which he won.

The biggest name in Big Brother: Celebrity Edition is *NSYNC's Lance Bass. The singer has appeared on Dancing with the Stars where he placed in third, and has also had lots of hosting appearances and celebrity game show cameos. Also, Bass is reportedly a Big Brother superfan.

What do you think of this cast of 10 Big Brother: Celebrity Edition houseguests? The official announcement is five days away and then the short season begins on February 7.
