Earlier this week, 50 Cent attended the International CES with an all too familiar face in his entourage: Ken Shamrock. But, what was Shamrock doing there? Are they working on a new venture together? Not really. At 49 years old, Shamrock is no longer fighting for a living and instead, he's working for a company which provides security for high-level clients, like 50. 

After his presence at the CES started making the rounds, Shamrock hopped on Twitter to confirm what he was doing there. 

So, yeah, now you really shouldn't mess with 50 Cent.
