Rapper 50 Cent is refusing to pay attention to disparaging comments made by his former G-Unit bandmate and friend Tony Yayo, insisting he has done everything he can for his longtime sidekick. Yayo recently took to his Instagram.com page to announce his retirement, revealing he was no longer part of G-Unit and accusing his former pal of abandoning him and fellow group member Lloyd Banks. The In Da Club hitmaker has now hit back, insisting he gave both Yayo and Banks the best chance possible to make it in the music industry on their own. He tells Billboard.com, "I had a wonderful journey with the people I grew up with. I think the frustration comes from shock, probably, that it's not everything they wanted it to be. "It's not a secret, it's a known fact that he (Yayo) actually came home from jail with a million dollars and a Bentley. Like, 'What do you want?' These guys are millionaires. They've made millions of dollars. Why do that then..? I don't know what the goal was." He adds, "I don't believe in looking back. I can care less about things that's (sic) happened in the past. I'm looking forward, at prosperity. "I've learned the same person that tells you you're a piece of s**t, tells you they love you when the right song comes out... so you can't be affected by 'I hate you' - because it won't allow for something good to come in."
