The 29-year-old singer and long-term boyfriend Jason Trawick (39) were secretly engaged after he popped the question by writing the pop star a romantic poem.
After filling the ground floor of the couple’s Los Angeles mansion with roses and candles, Jason reportedly presented Britney with a flower-shaped diamond ring, according to The Sun newspaper.
An insider said: “She’s on cloud nine.”
Spears has two sons, Sean Preston (5) and Jayden James (4) with second husband Kevin Federline.
The Toxic hitmaker is also said to be keen to have another child, her first with Jason, but only wanted to do it once she had tied the knot again.
The source added: “Britney is desperate to settle down again and have more children. But she is very traditional and didn’t want to start a family with Jason until they’d tied the knot.”
Britney — whose first marriage to childhood friend Jason Alexander was annulled just 55 hours after they said, “I do” in Las Vegas in 2004 — is now said to be planning a “low-key” ceremony in Hawaii once she has completed her upcoming world tour. — BangShowBiz
