Ashley Greene, Joe Jonas Gush Over Coachella In Today's Tweet Dreams

What did you do this weekend? If the Twitterverse is any indication, practically everyone in young Hollywood would have to answer "Coachella" and make us terribly jealous in the process. Everyone from "Twilight" vamp Ashley Greene (pictured) to songstress Katy Perry were gushing about the event. The "Firework" singer tweeted praise for Empire of the Sun and Kanye West before exclaiming, "...do it allllllllllllllll again!!! #REALWORLDCOACHELLA!" Joe Jonas also gushed over Empire of the Sun and Kanye, but added a few other favorites when he tweeted, "#Coachella you ruled! Foster the people, Chromeo, Kanye, Mumford, Empire of the sun... just a few of my favorites! WoW! #canwedoitagain?" Joe's ex Ashley was also in attendance, but if they bumped into each other the awkwardness obviously didn't outweigh the fun that is Coachella. She tweeted, "Such a crazy fun weekend of amazing music and amazing people! I'm so glad I got to experience that. #Coachella"

In less musical news, Kourtney Kardashian celebrated her birthday today. The reality star turned 32 (these Kardashians barely seem to age, seriously), and friends tweeted their birthday wishes. Sis Khloe tweeted some old family photos for the occasion, posting, "Celebrating @KourtneyKardash's birthday with some of my faaaavorite family pics http://bit.ly/hoqKWL." Friend Brittny Gastineau spread the love with a simple (and less embarrassing) "Happppy bday @KourtneyKardash I loveeeeee you."
