'No Strings Attached' Opens In Theaters, Katy Perry Announces Her Tour In Today's Tweet Dreams

Got a hot date this weekend, but don't know where to take them? Rest easy, Crushers, Ashton Kutcher and Mindy Kaling have a solution for you! The actress urged from her page, "Take your beau or miss to No Strings Attached!" while the flick's leading man (pictured here with his co-star Natalie Portman in a scene from the movie) promised, "Make your date plans for tonight. No Strings will not disappoint!" Even his date, wife Demi Moore, gave the film a thumbs up as she tweeted, "I love No Strings Attached! It's sooooo good! Smart funny and a great ride!!!!"

Speaking of great pairings, Katy Perry has let fans know who will be joining her on her upcoming California Dreams Tour! Singer Robyn announced from her page, "Yes! Im opening up for @katyperry on some of her american dates this summer. As soon as i have the dates, you will. Watch out!" as Katy excitedly responded, "@robynkonichiwa and I will be dancing up a storm watching your set! Can't wait, BTE!... best tour ever!" Katy later wrote, "I feel like this tour is building a bridge between the hipsters & the popsters. Hip-Pop is so 2011. Get wit it. #californiadreamstour!"
