Britney Spears has announced her engagement to her boyfriend Sam Asghari with an exuberant post displaying a diamond ring engraved with the word “lioness”.

She wrote “I can’t fucking believe it!” with an Instagram video post in which she winks, kisses a smiling Asghari on the cheek and answers “yes!” when he asks if she likes it.

Asghari, an actor and personal trainer, posted his own photo of Spears showing her ring to the camera.

The news comes days after her father filed to end the court conservatorship that has controlled the singer’s life and money for 13 years.

Asghari’s manager, Brandon Cohen, confirmed that the pair were engaged. “The couple made their long-standing relationship official today and are deeply touched by the support, dedication and love expressed to them,” Cohen told Reuters.

The four-carat diamond ring is engraved inside the band with “lioness” because it’s his nickname for her, ringmaker Forever Diamonds NY said in a statement. Its master jeweller, Roman Malayev, told Page Six: “Their journey together has touched people around the world and we’re so excited to be a part of their forever … We are thrilled to congratulate Britney and Sam on their recent engagement.”

The couple met on the set of the Slumber Party music video in 2016.

The singer told a court in June she wanted to marry Asghari and have a baby with him during an impassioned plea to end the conservatorship, but said she hadn’t been allowed to remove an intrauterine device for birth control or even drive with him.

Legally, Spears can get married, but the conservatorship must approve it as with other major life decisions.

Spears was previously married to Kevin Federline, with whom she shares custody of two sons, aged 14 and 15. She was briefly married to childhood friend Jason Alexander in 2004.
