Summit Entertainment broke the news via the "Twilight" Facebook page, along with a photo of the artwork for Mars' single.
The artwork looks like a painting, seemingly created with watercolors or oil paints. The picture depicts a brooding Mars in black silhouette, holding an umbrella in one hand, a bottle of something in the other. He's sitting in a chair, posture slightly slumped and legs spread out in front of him. The background is colorful, with swirls of paint dripping down the frame. "It Will Rain" is written in prominent thick black lettering to the right of Mars.
In knowing Mars' style, we expect the song to be sweeping, epic and possibly heart-wrenching. In being named to the illustrious ranks of "Twilight" soundtrack artists, the rising star and VMA nominee joins artists like Paramore, the Black Keys and Muse.
When we last checked in with "Breaking Dawn" director Bill Condon at Comic-Con, he confirmed they were putting serious thought into the crafting of the soundtrack, courtesy of composer Carter Burwell, who scored the first movie, as well as careful consideration of which acts to include. And while the director would not confirm Pattinson's inclusion on the soundtrack, he hinted that some of the musically inclined castmembers might lend their talents to a track or two.
"We're just figuring out [the soundtrack] now," Condon said during MTV News' "Breaking Dawn" Comic-Con takeover. "We have a lot of [songs]. We have like 15, I think."
