Marquise Jackson took to Facebook page on May 18 to criticize his father for failing to show for the celebration, which took place at his private school in Atlanta, Georgia last week.

Alongside a photo of the youngster, dressed in the traditional cap and gown and hugging his mother Shaniqua Tompkins, he wrote, "Yea (sic) I broke down. I was really excited to see my pops at my graduation but he never showed up smh (shaking my head). My sister and mama is always there for me just know that you wasn't. I did it without you."

The rapper has endured a rocky relationship with Marquise and his mother in the past few years and publicly disowned him in a series of posts on his Twitter last July.

However, sources tell TMZ that 50 Cent didn't intentionally skip the graduation -- he wasn't invited. Instead, the rap superstar was in his native New York attending a charity event.
