The cast has gotten girthy
These are not some sexy 30-something year olds anymore.
The vast majority of them have grown hefty. Jax and Stassi look like complete different people now. Jax's GF does not belong in LA or the service industry in WeHo with that size on her. She was wearing what looked like a girdle to the pool, passing for a swim suit.
Katie now officially looks like someone's mom.
Only Ariana, the Toms and Kristen observe their weight and looks it seems. Stassi is sad now, b/c she is fat. Pure and simple. The whole plotline about her heartbreak in regards to her millionth break-up w/ whichever guy is complete BS.
And she persists being a grade A c unt... Still!
