So she is a reality star... Great. How talented..
She is not 'famous' for her modelling career. That is a joke. She happened to do modelling for money when younger, she was not known for it

Wow.. she is famous for being in more reality TV. Almost every reality Star is the US go on The Apprentice etc.
It's also very easy to be on the NYT best sellers list many reality stars achieve this, you don't actually have to sell many copies at all to do this, you don't need talent, there is an endless list of people who have achieved this [SO MANY] that even you would agree lack talent

Yeah James was the leading role in a very popular TV show. He is famous from his talent and skills. He has a much larger following than Brandi due to his acting and because he became a celebrity through credible means
Zendaya also only had starred in kids TV shows and this year she has became a worldwide hollywood star, just because you're leading a role in a kids show does not mean you have no talent -thousands apply for these roles. James was successful and became famous through his talents.
Being a reality TV star doesn't actually require talent - it usually consists of talking smack or marrying someone rich
Brandi was actually a stand in for CBB as clearly the producers didn't feel that she was famous enough to join the cast of 'Celebrity Big Brother' she was clearly paid very little to get her as a last minute substitution.
Stay uneducated hon
