Romeo Santos, the former lead singer of the popular bachata group Aventura, has taken a new step in his career, venturing out on his own as a solo artist. Mixing his signature bachata flair with some R&B, he is showing fans a whole new side on his debut album, Formula, Vol. 1.

Hoping to spread his unique sound and style to a mainstream audience, Santos enlisted Lil Wayne for his latest single, "All Aboard."

"This song 'All Aboard,' that tune allowed me to expand and kind of offer my audience something totally different because it's not bachata — I'm singing English and that was really fun," Santos recently told MTV News. "I was a little nervous about that, but people actually really accepted it."

Santos and Weezy recently shot the video for "All Aboard" in Miami; he called the clip "sexy," "seductive" and "elegant," but also revealed that this collaboration came very close to not making his album.

"I was just like, I like the song but it's missing something, and at first I couldn't figure out what it was," Santos said. "What we did was we left 16 bars open, and I was like, you know, who would rip this track? Lil Wayne. So we reached out. It barely made the album because he's a busy dude, so he actually got on the record two months after we submitted it. It was like, if we don't get his vocals in the next two days we hit, and we got it, so we made it and the song is just really great."

Wayne isn't the only artist Santos pulled in for his album. On his last single, "Promise," he teamed up with Usher, who last week joined him onstage at Santos' first of three sold-out shows at New York's Madison Square Garden.

"I felt at that moment once again I was going to revolutionize bachata 'cause it was the first time that you hear an artist from the mainstream singing bachata," Santos said. "It was a big deal."
