The couple announced their engagement in 2021, around the time the singer was formally freed from the involuntary conservatorship that had controlled her career since 2008.

Spears recently revealed that her father Jamie Spears, who served as conservator, earned $36m (£28m) during the course of the 13-year legal arrangement.
