Dianna Agron’s Exclusive Invite and Other Celeb Twitpics of the Week

Dianna Agron was the proud holder of an invitation every fashionista would envy, a front row seat with her name on it at the Louis Vuitton show. Was it worth the anticipation? “Vuitton glamour full stop. A train, models with porters. It was truly beyond. Hooray for MJ, Fabrizio & LV,” tweeted the actress.

“What's the word for this? I believe it's MAJOR! So proud of @AnneV killing it at #miumiu!!!!!!!!!!!!” tweeted Adam Levine in support of his girlfriend, model Anne V, who opened for the designer and also walked for Prada and Roberta Cavalli in Milan.

That is to say, she and her mom got a haircut together. “My beautiful Mom and I got a new haircut!!! Thank you Michel Aleman. We love you!” tweeted the model. What do you think of those sleek side-bangs?

Jessie J kept fans updated backstage at the Future Music Festival in Sydney, Australia last week. “LET'S DO THiS!” she tweeted, showing off her super 90s bubble gum denim short suit.

Spring is in the air, and on some celebs’ nails. “My ready for spring French manicure by @nettiescrub !” tweeted Zooey Deschanel. From these nails to Katy Perry’s hair to Stella McCartney’s looks this season, it seems undeniable that blue beauty is back.

For Paris Hilton, fashion is all in the family. “At my parents house with Pixie. Wearing 1 of my @PHpurses, my new sunglasses line & a @KathyHilton dress,” tweeted the socialite.

Jessica Simpson looked like she was about to pop in the pic she tweeted from the beach, although it was tame compared to the bare baby bump Elle cover that caused a stir last week. “We are loving Laguna...and yes, I'm wearing flip flops!” joked Simpson, who has somehow been balancing that belly on heels throughout her pregnancy.

In the internet age, it’s easy for fans to dig up celeb photos from the past, but Rosario Dawson doesn’t seem to mind. The website Celeb School Pics found this sweet photo of the actress as a kid, and Dawson proudly re-tweeted it. “Awww! That's from Sesame Street!” she wrote.

“Happy Saturday!” tweeted Nicole Richie, who it seems is as susceptible to the power of horses as any other girl.

Kanye West’s go-karts were a highlight of Paris Fashion Week, and model Anja Rubik lived it up on one after a busy day of catwalking. “On a go kart :) at the after party,” she tweeted.
