The 23-year-old singer - who recently reunited with Rihanna despite still being on probation for beating her in 2009 - has admitted a lot of his new music was inspired by a former love interest, believed to be Karrueche Tran, who he dated on and off for a year. Chris told MTV News: "The song and the album title `X` has a couple different meanings. It can refer to an ex-girlfriend, in terms of you always look forward to moving forward from. "It`s also about being a reject in a sense. In me being myself, being able to grow up, me not always hanging around the right crowd or doing the right thing all the time - it`s me saying, `I`m over it. I`m past the bulls**t now." The 24-year-old model dated the `Don`t Wake Me Up` hitmaker, who she has a clothing line with, before he left her in October 2012 to reunite with Rihanna. Chris revealed earlier this week that he thinks about having a "perfect" family with the 24-year-old `Stay` singer in the future. He told Ryan Seacrest on his KIIS-FM radio show: "It`s in a part of my brain, definitely. Right now I have a lot more people to take care of as far as my family, as far as inspiring artists I`m working with. Everything I`m doing now is focused on me giving back. "The family is there. It`s going to be what it is. It`s going to be perfect. Hopefully that`s in the future and I can wait it out."
