Well, 50's been pretty busy ever since.
Over the weekend, he launched a number of verbal attacks directed at Ross on his Web site, ThisIs50.com.
On Saturday, 50 started with a video blog where he denied Ross' claim that he wilted at the sight of the Boss during last year's BET Hip-Hop Awards. "I don't remember seeing him," 50 said. "You're so unimportant, I don't even remember."
In the clip, Fif also said he'll relentlessly attack Ross, and like Ross, he won't stop because of label pressure.
"I'm deciding to f--- your life up," 50 said into the camera. "Rick Ross, I'm gonna f--- you life up ... for fun. This is not new. I do this all the time."
50 went on to explain that he purchased court transcripts from Ross' family court case with the mother of one of his children (presumably in response to Ross' jabs about last year's "suspicious" fire at the home of one of 50's ex-girlfriends). He then warned Ross, "I think it's fair to say that I know you now and everyone else will know you."
Later that day, an animated parody of Ross and 50 appeared on the site. In the video, 50 is shown locked up in jail with Ross serving as a correction officer. Throughout the clip, 50 taunts Ross: "Officer Ricky!"
On Monday (February 2), 50 showed just how familiar he is with Ross now. The rapper featured himself in a clip with the mother of Ross' son, Tia Kemp.
During the eight-minute-long video, 50 interviews Kemp, who mocks Ross' boasts on his records.
"It' sort of embarrassing to me, because as you listen to his raps you would definitely believe him," she said of Ross' financial status. "It was surprising to see he spends $200 dollars a month on food, $300 dollars a month on clothes, his jewelry is rented [and] possibly not real, his cars are being leased, he doesn't know where the money came from to put a down payment on a million-dollar home. I just want to prove the facts today. It's all real, coming from Tia."
Kemp told 50 that when she dated Ross she moved in with the rapper during her pregnancy. While she was cleaning the house she learned Ross had once been a correction officer, which she said he denied. According to Kemp, his sister confirmed the matter that later was referenced by TheSmokingGun.com.
A little more than halfway through the video, 50 ends the interview with Kemp, promising more to come. He then takes Kim on a shopping trip through New York, where the pair stop at a fur store for a coat before later going to the Gucci store to buy shoes.
"This is gonna be fun," 50 said of mocking Ross.
