Calvin Harris Promotes New Music Video on Instagram After Deleting All Pics With Ex Taylor Swift

It's back to business for Calvin Harris.

After news broke Wednesday afternoon that his ex Taylor Swift had seemingly moved on with Avengers star Tom Hiddleston, the deejay producer is conducting business as usual with his latest Instagram posts.

"F R I D A Y @badgalriri," he captioned two photos of Rihanna on set of their music video for the song "This Is What You Came For."

Harris' late night post came shortly after he erased all traces of his relationship with Swift, 26, from his Instagram. The "Shake It Off" singer also erased photos of her time with Harris, including romantic snaps from their anniversary vacation in March.

After photos showing Swift getting cozy with Hiddleston were released Wednesday by U.K. tabloid The Sun, a source told PEOPLE that Harris, 32, was unaware of a budding romance between the new couple, who were photographed exchanging kisses in Rhode Island.

"He did not know Taylor and Tom were together," the source said, while a Harris pal added that the star had "moved on" and was "happy."

Although Swift and Harris only split a few weeks ago, another insider close to the couple told PEOPLE that there was "no drama" involved and that cheating didn't play a role in the downfall of the relationship.

"Things just don't work out sometimes," the source continued.

A rep for Hiddleston declined to comment, and reps for Swift and Harris have not commented.
