'Braxton Family Values' Sneak Peek: Tamar Braxton Compares 'Celebrity Big Brother' to Prison (Exclusive)

The reality star went on to win the CBS competition series.

Being in the Big Brother house isn't easy. 

ET has an exclusive sneak peek at this week's episode of Braxton Family Values, in which Tamar Braxton prepares for her time on Celebrity Big Brother. While explaining the rules to sister Towanda Braxton and their mom, the reality star compares being on the CBS reality show to life in prison. 

"It is [like being in prison]! And you can't talk to anybody. It's like being in a hole," Tamar says. "I feel like I am [prison smart]. I can make the top prison food, the ramen noodles and the tuna fish. It's absolutely amazing."

"You can't write stuff down. You can't take books... you can take a bible," she continues of the show's rules, before revealing what would be her biggest struggle in the house: "not talking to my baby." 

Tamar, who shares 5-year-old son Logan with her ex, Vincent Herbert, called him her "entire life." 

"This is going to be like, a struggle for me, being gone for him, for like, a day. What about 30 days?! I can already tell that the hardest part about this whole thing is going to see if I can be away from my baby that long," she confesses.

Tamar ended up winning the reality show in February, and revealed she was most excited to share her $250,000 winnings with her son. 

"Thank you guys for being my life-long friends," she said to her fellow housemates during the finale. "Thank you guys. I am so grateful and now I get to buy my baby a house!"

After their reunion, Tamar told ET she was looking forward to turning her Celebrity Big Brother success into something more. "There's a couple things going on with Tamar," she said, referring to herself in the third person, with a laugh. "My hope is to be the Cardi B of TV!"
