Britney Spears 'over the moon' after engagement to Sam Asghari: source

Britney Spears could not be happier after her suprise engagement at home with boyfriend Sam Asghari.

The pop icon is 'ecstatic' following the proposal, as revealed by an insider.

"Britney is ecstatic," said the source, who giddily showed off her brand-new diamond ring on Instagram.

In a statement issued by Asghari's manager Brandon Cohen, the couple is "deeply touched by the support, dedication and love expressed to them."

Cohen added that Spears' new bling was designed by New York City jeweler Roman Malayev.

Earlier, a friend of the couple said they are ready to take things to the next level and plan to tie the knot.

"He's ready for marriage and kids with Britney and is serious about the relationship. She wants to take that next step and have that full life with him," said the friend. 

"As a couple they've hidden how they've really felt even from people close to them because they were anxious and scared, but now it's all out there," they added.
