Jason Trawick has just been removed as Britney's co-conservator ... TMZ has learned.  Jamie Spears is once again her sole conservator.

Britney Spears
and Jason Trawick have broken up ... TMZ has learned.

The couple got engaged back in 2011. Trawick started out as Britney's agent, the duo started dating and he eventually became her co-conservator along with her dad, Jamie Spears.

Multiple sources connected to the couple tell TMZ ... Jason didn't want to make the announcement until he was taken off the conservatorship.  Interestingly, lawyers for the conservatorship are in court right now, along with Britney's dad, Jamie Spears, so it's possible Jason will be removed today.

Sources say it was a "friendly breakup" and Britney and Jason will remain friends.  As for why they split, we're told they just "grew apart."

The timing's pretty interesting considering Brit recently changed agencies, heading to CAA ... an indication Trawick was no longer involved in managing her career.

Britney told ...  "Jason and I have decided to call off our engagement. I'll always adore him and we will remain great friends."

Trawick also issued a statement saying, "As this chapter ends for us a new one begins. I love and cherish her and her boys and we will be close forever."
