Ansel Elgort, who starred in the recent film The Fault In Our Stars, has broken up with his high school sweetheart Violetta Komyshan.

A source explained the reason for their breakup was because the young actor had simply become too busy. "They tried to navigate his commitments," the insider told Us Weekly, "but between filming and press for the movies [it got difficult]."

Though they split, the sourced added that the 20-year-old Elgort and Komyshan's split was an amicable one.

It hasn't been revealed when they called it quits, but Elgort was spotted on Saturday at his sister Sophie's wedding all by himself, though he was said to be in the middle of everything. He sang to his sister and a wedding guest said he was "dancing up a storm with friends and family."

Elgort recently took part in the popular ALS Ice Bucket Challenge early last week and then followed it up by challenging author John Green, Nat Wolff and Dylan O'Brien.
