Britney Spears Addresses Engagement Haters In Bikini Bottoms

Scroll for the video, plus a photo shared to Asghari's Instagram. Britney, who had told a Los Angeles court judge that her conservatorship was preventing her from marrying Sam - and having a baby with him - is clearly having the upper hand, this likely due to dad Jamie Spears this month filing to end his daughter's 13 years of conservatorship.

While it was fourth finger flipping the bird and flaunting the ring on Sam's Instagram yesterday, it was shock and joy in joint selfie action on Spears' account as she broke the news.

Taking to her caption as she wore a frilly pink top and showed off her diamond ring, the Grammy winner wrote that she "couldn't f-cking believe it." Comments, which largely congratulated the singer, are, however, now dominated by fans warning Britney to protect her vast estate.

Sam has since addressed the prenup frenzy and with humor. "Thank you for your concern about the prenup!" he wrote on Monday, jokingly adding: "Of course we're getting an iron-clad prenup to protect my Jeep and shoe collection in case she dumps me one day."

On Tuesday, Britney took matters into her own hands. The blonde updated for her 34 million Instagram followers while rolling around stone flooring by her pool and wearing only pink bikini bottoms. Highlighting her iconic figure, the singer wrote: "People love to talk sh-t so...KISS MY -SS!!!!"

TMZ reports that Spears is already in prenup talks to protect the fortune she amassed by being an A-List pop star, although no details were provided. The singer met her beau on the set of her "Slumber Party" music video.

Yesterday, Sam's talent manager opened up to Page Six, saying: “The couple made their long-standing relationship official today and are deeply touched by the support, dedication and love expressed to them/ Roman Malayev from NYC is the ring designer. He couldn’t be more happier to be involved and make this a one-of-a-kind ring.”

Britney's ring is said to be a “4-karat round brilliant stone in a platinum cathedral setting enhanced with a floating solitaire design.” If she goes ahead and marries Asghari, it'll be her third marriage after failed ones to Kevin Federline and childhood pal Jason Alexander.
