50 Cent has ended his partnership with Sleek Audio over the “Sleek by 50″ line of headphones. The Sleek by 50 headphones debuted in January. 50 Cent is starting a new line of headphones through a new company and will compete with Sleek Audio. 50 Cent terminated a tri-party agreement that was made between Sleek Audio, G-Unit, and TV Goods.

50 Cent is not too pleased with WorldStarHipHop.com. He sent out a tweet to his 3.8 million followers about how he got the website shut down by Homeland Security. The website went down temporarily, but was back online within 24 hours. The founder of WorldStarHipHop.com said it was a problem with his servers. “I don’t know why people underestimate me. I just shut down WORLDSTAR for future advertising contact thisis50.com suckers lol,” said 50 Cent in a couple of tweets. “I put worldstar to bed, you don’t believe try me I will shut your shit down. Lol.” 50 Cent said that WorldStarHipHop.com uses 50 Cent’s content and images without permission and he filed a lawsuit against them in November 2009.

This is the first time I have ever heard of some tweets substantially increasing the stock price of a penny stock. Rapper and investor 50 Cent sent out the following tweets:
1. “[H&H Imports] Stock went from 5 cent to 10 in one day. You can double your money right now. Just get what you can afford.”
2. “[H?&?H Imports has]…15 products this year. If you get in technically I work for you. BIG MONEY.”

Sleek Audio and Curtis “50 Cent” Jackson have partnered with each other to launch a new pair of headphones. 50 Cent designed the headphones and they are the first to have Wireless Hybrid technology using military-grade metals. Below is the full press release:

Curtis Jackson (known by his rap artist name 50 Cent) has invested in Gunnar Optiks, a sunglasses company that makes indoor, outdoor, and 3-D viewing products. 50 Cent runs several businesses such as a clothing line, a record label under Interscope, and he made $100 million when Coca-Cola bought out the Vitamin Water parent company. Gunnar sells 3-D sunglasses for between $70-$200. 50 Cent first expressed interest in Gunnar when he discovered them at a charity event hosted by Justin Timberlake. At first Gunnar was interested in 50 Cent endorsing the products, but the rapper was more interested in being a proper investor. 50 Cent is endorsing the products on Twitter also. [Fast Company]

Keenan Cahil is a popular YouTube celebrity that is best known for lip-synching popular songs. In his latest video, he starts doing a song called “Down on Me” and 50 Cent decided to pop in and join him. Keenan Cahil (BeenerKeeKee19952) has a total of about 66.1 million total upload views on YouTube. 50 Cent definitely knows how to market himself and I’m sure this video will spread like wildfire. Check out the video below:

Vevo is geared to launch tomorrow. As many of you know Vevo is going to be the Hulu of music videos. This means that those of you that are sick of MTV playing more reality shows than music videos these days will finally be able to get your fill of music videos again in one central place. Sony, Universal Music Group, and EMI Music have all agreed to place music video clips on Vevo too. YouTube technology will be used to power the video streaming. In order to promote the new service, Vevo has given 50 Cent a baseball bat to bash up some TVs playing his music video. Just in case you don’t get the metaphor in the video, Vevo wants you to stop watching music videos on TV and come to their website instead.

Rapper Fabolous who is known for the songs “My Time,” “Throw It In The Bag,” “Make Me Better,” “So Into You,” etc. Fabolous grew up in the Brooklyn area of New York which is within 15 miles where 50 Cent was raised in South Jamaica.

On October 6th, Fabolous wrote the above Twitter message and 50 Cent’s blog wrote that he wrote the message because he wasn’t invited to the ThisIs50 Fest. The ThisIs50 Fest had artists performing such as Kid Cudi, Wale, Wyclef, G-Unit, Slaughterhouse, Maino, Jadakiss, Papoose, Crooked I, Uncle Murda, Jim Jones, and Juelz Santana.

Fabolous wrote “Its interesting to c 50 Cent unit wit NY artists when he’s 1 of the reasons NY hip hop became so isolated & crumbled..DO u agree NY??” Thats a pretty bold statement considering that 50 Cent is one of the most prominent rappers from New York.

50 Cent personally responded to the statement on his blog:

Reading what Fab said about me on Twitter was disappointing.
I have extended myself to Fab personally to allow him to expand himself as an international Touring Artist.
I Thought we were Friends but that’s cool.

Law #2: Never put too much trust in Friends, Learn how to use Enemies
Be wary of friends—they will betray you more quickly, for they are easily aroused to envy. They also become spoiled and tyrannical. But hire a former enemy and he will be more loyal than a friend, because he has more to prove. In fact, you have more to fear from friends than from enemies. If you have no enemies, find a way to make them.
—50th Law of Power.
Am I 50 Cent or Am I Machiavelli? Dammmm!!!

After 50 Cent responded and Twitter users were angry with what Fabolous said, the rapper from Brooklyn immediately regretted what he wrote as displayed in the below tweets. 50 Cent has about 1.7 million followers on Twitter and Fabolous has about 300,000.
