"He's still touring and going overseas now," while Wilde is "focusing on her kids and her work in LA."
Another friend of the couple speaking to People similarly stated "different priorities that are keeping them apart."
A source also told Page Six that Styles and Wilde were on a "break," adding that there is "no bad blood" between the couple and neither party left the other.
"This is the longest relationship Harry has ever been in, so clearly they have a special bond," the source said.
Representatives for Styles and Wilde did not immediately respond to HuffPost's request for comment.
Earlier this week, Wilde was spotted at Styles' Los Angeles show with daughter Daisy, 6, and son Otis, 8, her children with ex-fiancé Jason Sudeikis.
