After four years of dating actor and personal trainer Sam Asghari, pop sensation Britney Spears has said yes to the 27-year-old. The singer made the announcement through her Instagram page, with a video post of the two, and her flashing a diamond engagement ring.

Sam has also shared the post on his own social media page, with the ‘Crazy’ singer flashing the ring on her ring finger.

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

People reports that the actor had popped the question in her Los Angeles home on Sunday, and her diamond sparkler is custom-designed by Roman Malayev, founder of New York City jeweller Forever Diamonds. According to the jeweller, the band of four-carat diamond is engraved with the word “Lioness”, which is Asghari’s nickname for her.

The two first met on the set of her Slumber Party music video in 2016, before dating in . It will be Britney Spears’ third marriage; she briefly wedded childhood friend Jason Alexander in Las Vegas in 2004, and subsequently, dancer Kevin Federline, but later divorced in 2007. They share two children, Sean and Jayden Federline.

The news also comes days after her father, Jamie Spears, filed to end the court conservatorship that has placed him in control of the singer’s life and money for over a decade.
