Britney Spears is hearing wedding bells loud and clear!
Spears, 39, who is engaged to her fitness trainer-actor boyfriend Sam Asghari, 27, “wants to get married as soon as possible,” a source close to Britney tells PEOPLE in this week’s issue.
“She would love a beach ceremony at a tropical destination,” adds the source. “It will be a small wedding.”
Asghari asked for Britney’s hand on Sept. 12, five days after Britney’s dad, Jamie Spears, filed a petition to end the conservatorship that has lasted 13 years.
“I can’t f—ing believe it,” she captioned an Instagram clip revealing her new rock, which Asghari’s manager Brandon Cohen said was designed by N.Y.C. jeweler Roman Malayev founder of Forever Diamonds.
And while Britney “knew that the engagement was coming,” it was “still a surprise,” according to the source. “Sam proposed at her house, and she loves the ring. She is ecstatic.”

This will be the third marriage for Britney, who briefly wed childhood friend Jason Alexander in 2004. She went on to marry Kevin Federline, with whom she shares sons Sean Preston, 16, and Jayden James, 15. The two filed for divorce in 2006 after a total of two years.
Britney made it clear how she watned to ger married once again when she testified in a June 23 conservatorship hearing.
“I don’t feel like I can live a full life,” Britney said then of the conservatorship, where her father and others have made her personal and financial decisions since 2008. “I want to be able to get married and have a baby.”
The two met on the set of her 2016 “Slumber Party” music video.
But allegedly, the past conservatorship “made it clear that Sam was not allowed to marry Britney. Now with Jamie more out of the picture, Sam was finally able to propose.”
As Jamie, 69, is still the conservator of Britney’s nearly $60 million estate — and will continue to be until at least the next court hearing on Sept. 29 — he has allegedly begun working on the couple’s prenup.
“Britney understands that this is necessary,” says the source.
Asghari teased on Instagram that they will have an “ironclad prenup to protect” his Jeep and shoe collection. At the end of the day, he just wants Britney “to be happy,” he recently told Men’s Health. “Happy wife, happy life.”
