G-Unit head 50 Cent has reportedly fired back at reports claiming his teenage son threw a fit over him not attending his high school graduation. #NotSoFast

According to reports, Fif’s ex-girlfriend is responsible for the now-infamous no-show.

50 Cent didn’t abandon his son on high school graduation day — despite an emotional Facebook post from the kid — instead 50 claims he was intentionally blocked from attending by his son’s mother … at least that’s what 50 is telling friends. Sources close to the rapper tell TMZ, Fiddy is extremely hurt and upset by the photo his son Marquise Jackson posted on Facebook Sunday crying in his cap and gown while hugging his mother. (TMZ)

Reports also claim the celebration went down in Atlanta while 50 attended a New York charity event.

50 disagrees … telling friends he was never told when or where the graduation ceremony was, or he would have been there. FYI, the ceremony was at Marquise’s private school in ATL (the same school 50 reportedly foots the bills for). We’re told 50 spent last weekend in NYC for a charity event. (TMZ)

A screenshot of Marquise Jackson’s alleged Facebook post has started to scatter across the Internet.

“Yea I broke down. I was really excited to see my pops at my graduation today but he never showed up. My sister and mama is always there for me. Just know that you wasn’t. I did it without you!” (MStarz)

The latest reports claim Marquise never posted the 50-related remarks.

According to Marquise’s sister, the Facebook page that posted this photo is not Marquise’s real page. Although the page appears to have over 5,000 friends and 200k followers, some including friends that know Marquise personally and attended his graduation. His sister, Mia, provided his Twitter and Instagram and says they’ve been trying to get the fake page shut down. “The page has been there for years. We tried to get it deleted. Whoever runs that page has a lot of time on his hands because they create pages of our mother and I and have them correspond with one another as if it’s us, but it’s not.” (Baller Alert)
