iOS 5 promises to make your life easier with new upgrades and tools and we have a sweet iOS 5-optimized app for all you pop-culture junkies. The newly updated PopSugar Mobile for the iPhone and iPod Touch has launched with Twitter integration to bring you even more celebrity goodness!

Alongside PopSugar's up-to-the-minute news stories and photo galleries of your favorite stars, the upgraded app will also show you live tweets from verified celebs and related tweets inside stories. You can even weigh in on posts by commenting or tweeting at PopSugar, follow, or send a tweet to a celebrity without ever leaving PopSugar Mobile. It's the best way to keep up with news and events on the go. Plus, of course, you'll still have access to feeds from the rest of the PopSugar Network sites like FabSugar, TrèsSugar, GeekSugar, and more.

Get a closer look at the app in the photo gallery, then head on over to iTunes to download now!
