Rihanna Returns!

A few days ago, Jay-Z debuted "Run This Town," the second single from his upcoming Blueprint 3 album. The real news, however, was the vocalist singing the hook — Rihanna.

The chart-topping R&B singer faced tough times this year after a violent scrape with then-boyfriend Chris Brown. While she laid low these last few months, the singer is back and dropping hooks on what will be one of the biggest rap singles of the summer, especially since the song features music and additional rhymes from Kanye West. Talk about a star-studded single!

Check out the song here on Jay-Z's MySpace page.This awesome new track, featuring a beefy guitar riff, is the perfect platform for Rihanna's triumphant return. The song reunites Jay-Z and Rihanna, whose previous collaboration was the massive hit "Umbrella," and as rap historians know, Hova gave West his big break producing much of the original Blueprint album back in '01. In other words, Jay-Z recruited with the people behind two of his all-time biggest collaborations to create one giant hit single.

It's always good to have a new Jay-Z single, but it's even better to see Rihanna return to the game. Rihanna, welcome back!
