50 Cent never misses an opportunity to take a jab at Diddy. Today (Nov. 4) is Diddy's birthday and the mogul celebrated earlier by releasing his MMM album for free. 50 Cent was determined to get under Diddy's skin though as he took to Instagram and trolled Diddy by posting an awkward photo while sarcastically wishing him a happy 46th birthday.

This is just latest instance of 50 Cent taking a chance to troll Diddy whenever he can. The two have been in a beef since 50 Cent became the spokesman for the Dutch liquor Effen Vodka last year. Diddy has been a 50/50 partner in Ciroc Vodka since 2007 and obviously 50 viewed him as a rival. Since late 2014, 50 Cent has taken plenty of shots at Diddy and won't seem to let up at all.

Despite his penchant for trolling on the Internet and work on his Starz show Power, 50 Cent is still focused on music. The G-Unit rapper recently announced a new mixtape called The Kanan Tape and unveiled the cover artwork. According to 50, the project will feature eight tracks. 50 is also working on his new album Street King Immortal, which is scheduled to be released sometime next year.
