Just a few weeks after debuting their single "Do It," Lil Wayne and Christina Milian have reportedly called it quits. ET reported that the two broke it off last month, after one year of dating. Wayne and Milian were practically inseparable for the past year, and it seemed like everything was going great with the former lovebirds; they had already released a number of collaborations together, including a single that would have been featured on Wayne's still not released Tha Carter V  that was titled "Start A Fire." The break up wasn't the only turmoil in Milian's life either, her sister Danielle lost her newborn child tragically last month as well.
