well, somewhat. hollywood is kind of like a cycle. in my opinion, unless if you are good at business like the Kardashians, then you will not last. every star is similar to a ticking time bomb until one day, they are not a star anymore. Paris Hilton is not relevant anymore because people got bored of her. we saw the scandalous, snarky blonde and followed her stories, until we got bored of the same scandals over and over and over again. similar to Kim Kardashian, she was falling off the wagon until she created her game and started a makeup line. i do not think Hilton is good at business due to her falling off. Britney Spears also got boring. We saw the innocent, flirty blonde and saw the potential she had. We saw her breakdown. But, she did not push herself out of the box she had and try something new. she wanted to be Britney Spears, not Britney Jean, and people got tired of the same persona from her. They both did not put themselves outside of the box, which makes them forgettable.
they became irrevent in 2011, and the rest was forgotten.
