Lightning strikes yet again for Calvin Harris and Rihanna. Nearly five years after topping the charts with “We Found Love,” the duo delivers a new summer anthem, “This Is What You Came For.”

“Lightning strikes every time she moves,” sings a seductive and confident RiRi over Harris’ uptempo bounce. “And everybody’s watching her, but she’s looking at you.”

This is another sign of chemistry for the two, who topped the Billboard Hot 100 for 10 weeks in 2011 with “We Found Love.” Since then, they have collaborated, but fans haven’t heard the results until now.

In 2014, Harris revealed that he submitted a song for ANTI. “I did one track [for Rihanna] and Tinashe wrote the top line, and I did all the music. I love it,” he told KISS FM UK. “But I don’t think she was into it. So I don’t know what is going to happen to that because it’s really good.”

That same year, he told The Sun something similar. “No I’m not on the Rihanna album,” he said. “I did a few things for it but they don’t get back to you. There are a lot of people involved! She listens to everything—I know that—but she’s got a strong idea and identity and an idea of what her album should sound like. But it’s OK because I’m working on my stuff and it’s going fine so I’m not concerned about it.”

It’s unclear where “This Is What You Came For” will land, but it could be on Harris’ follow-up to 2014’s Motion. Listen to the latest collab between Calvin and RiRi below.
