On Monday night, he shared a paparazzi photo of Kanye West dressed in head-to-toe Yeezy -- an over-sized dark grey T-shirt layered over a lighter grey long-sleeved shirt, baggy beige pants and beige Yeezy kicks -- at what appeared to be a gas station.
On September 11, 2007, 50 released his third studio album, "Curtis." The same day, Kanye dropped his third studio album, "Graduation."
At the time, Kanye made it seem like his album release coinciding with 50's album release was pure coincidence (Island Def Jam kept pushing back the date), adding that he felt it could only be positive for both rappers.
"When I heard that thing about the debate, I thought that was the stupidest thing," Ye said. "When my album drops and 50's album drops, everybody wins because you're gonna get a lot of good music at the same time."
Then-Def Jam president and CEO Jay-Z reportedly welcomed the competition, too, saying it would be prosperous for hip-hop music overall.
Though confident that "Graduation" would emerge victorious, Kanye said he'd be perfectly fine with losing to 50 Cent, saying he'd rather "be No. 2 on that day than come out and be No. 1 on a day nobody cares about."
50, however, felt the friendly competition favored only one rapper.
"It's great marketing -- for Kanye West," he told USA Today. "But I sell way more records than Kanye West, and I generate way more interest than Kanye West. They think they can match us up, but they'll find out when that week goes by and the sales come back. This is no rivalry."
He went on to tell Rolling Stone, "Mine will sell, and his will still be on the shelf."
"Graduation" debuted at No. 1 on the U.S. Billboard 200 chart, selling over 957,000 copies in its first week of sales and 2.7 million copies to date. "Curtis" debuted at No. 2 on the U.S. Billboard 200 chart, selling 691,000 copies in its first week of sales and 1.3 million copies to date.
One month before both albums dropped, 50 told SOHH he would end his career as a solo recording artist if "Graduation" were to sell more copies than "Curtis." He later retracted his statement, citing contract agreements with Aftermath Entertainment and Interscope Records.
