Katy Perry Puts Rumored Britney Spears Battle To Rest In Today's Tweet Dreams

Katy Perry had some pretty choice words for those who twisted hers on Twitter today. Mrs. Brand got caught up in a diva battle with Britney Spears after some bloggers suggested Katy took a swipe at Brit and her new "Hold It Against Me" video, which features the pop superstar showing some of her own products. In a Twitter chat with fellow artist Marina & The Diamonds regarding product placement in music videos, Katy wrote, "do it w/style & grace...Not so in ur face like some. U hv to get creative w/it. Some artists don't care tho, & u can tell." When some folks assumed Katy meant Britney, the "Firework" singer shot back from her page, "Dear tabloid media aka FILTH: pls note I expressed an overall feeling bout product placement, their roles in vids & the art of them being...complimenting or sticking out. Most, if not ALL popsters welcome deals w/products 2 offset costs of big budget vids in these recessional...music industry times. I'VE used them in MY vids before & am happy 2b able 2 make a better vid because of. Once AGAIN, stop pitting artists..against artist for ur sensational satisfaction & stick to what ur best @: lying, gossiping, exaggerating & overall lending a hand 2 the......deterioration of a generation."

On the less hostile end of the celebrity Twitterverse, artists like Natasha Bedingfield (pictured) are gearing up for a Motown musical celebration in honor of Black History Month that will take place at the White House tomorrow. The "Pocketful of Sunshine" singer told followers about her excitement over Thursday's event and performing for two people in particular who will be in the audience: President Barack Obama and First Lady Michelle Obama! Natasha wrote from her page, "Hey I'm inside the White House!!!!! I'm singing for the President and the First Lady tomorrow right inside their home!" Another one of the night's guests, John Legend, tweeted a pic of Natasha practicing an oldie for the concert, "At rehearsal for the Motown tribute. Natasha Bedingfield singing "tracks of my tears" http://twitpic.com/42zkvc." Luckily, the concert will be recorded on February 24 and broadcast on PBS on March 1 for all of Natasha's fans to see!
