Matt, 41, and Elle, 29, swapped vows during a breathtaking ceremony that happened outside by the sea.
"Mr. & Mrs. Bellamy," they both captioned two separate Instagram shots from their wedding.
Elle stunned in a strapless cream gown with Matt donning a matching tux for their big occasion.
Matt previously got engaged to Kate, 40, in January 2011.
Their relationship fizzled out three years later. Matt and Kate called off their engagement in December 2014.
The former couple share one child, an 8-year-old son named Bing.
The Almost Famous actress has since moved on with singer Danny Fujikawa. They welcomed a daughter on October 2, 2018.
