Blac Chyna and Rob Kardashian have called it quits again.

“They split a while ago. The wedding plans are off,” a source revealed to PEOPLE. “They are both trying to be mature about it. It was less dramatic this time.”

The pair went public with their relationship in January 2016.

Kardashian, 29, proposed to Chyna, 28, in April 2016, and by May the two revealed they were expecting their first child. Their daughter, Dream, was born in November 2016.
