Hip hop entrepreneur Russell Simmons’ Global Grind has purchased CelebrityTweet.com, which aggregates Tweets from celebrities, including Simmons (pictured) himself. Global Grind features a wide array of coverage geared towards hip hop fans, including videos, a number of celebrity blogs and political news. The company says it will continue to maintain CelebrityTweet.com as an independent site, although it will also now appear as a feed on the Global Grind home page. The company has landed SoBe Lifewater as a sponsor for both CelebrityTweet.com and its celebrity blogs. No word on a purchase price, although the acquisition comes only two months after Global Grind raised $2.6 million in new funding. More in the release here.
