Britney Spears announces her engagement to boyfriend Sam Asgari

Pop singer Britney Spears has announced her engagement to Sam Asgari, with whom she has long been friends.

The singer posted a video of the two of them together, showing off their engagement ring on Instagram.

Spears is in a legal battle to end her 13-year guardianship, which controls her personal and financial life.

Spears revealed that the terms of the agreement prevented her from marrying Mr. Asgari, or having more children.

The two met on the set of a music video shoot for Spears in 2016.

Asgari's manager, Brandon Cohen, confirmed the engagement news to People magazine.

"The couple have made their long-term relationship official today and have been deeply moved by the support, dedication and love expressed (from the public) for them," he said.

The 39-year-old has been married twice before, the first time in 2004, when she married her childhood friend Jason Alexander in Las Vegas, but they soon ended the marriage.
