First before she was Lady Gaga she was Stefanie the college student at NYU, doing the college thing....red solo cups and talent shows. The cups may have been used before this performance before the talent show:

Now...Katy Perry got some crap from some other blogs cause she appears to be wearing a larger brief cut of underwear under her workout tights...CAUSE SHE'S WORKING OUT!!!!!

Maybe she doesn't like the feeling of G string workouts, maybe Master P was in full effect, you don't know...jeez.

It's been kind of a sucky last 12 hours for your afternoon fool...Tuesday around noon I was eating some tasty tacos with my friend Kelly when all of the sudden my back right molar split in half, which I then swallowed before I realized it was busted...so let the self cheering up begin as I dread my emergency dentist appointment...

All women have cellulite, no really...look:

You don't know who that is...it's...

RIRI....mmmm. I like it...it gives her texture:)

Meanwhile, while the entire continent of Australia was offended by Britney's festive lip syncing, she got in some "Wear a bikini around your kids at mealtime" time in:

My tooth hurts...more please...

My dental insurance sucks and they're gonna take my tooth out with an ice skate like in Castaway...one more...please?!?!?!?

Thanks, those made me feel better:)

Britney's wearing a Snuggie!!!

Kim always has to be the attention-getter Kardashian

Brad Pitt always looks bored when he's out with Angelina Jolie...like really bored.

Nope, she just needs a stronger twitter password, look what went down Thursday:

Sadly, this is one of the most entertaining tweets I've ever seen on her Twitter page.
