According to Heat, the singer hopes to have a traditional white wedding with her partner, but will not rush into marriage following her splits from Jason Alexander and Kevin Federline.
Although a friend recently denied that Spears had proposed, a source said: "Now she's back on track with her life, the next step is to settle down properly with Jason - a wedding is so on the cards. They've already discussed it.
"Britney's relationship with Jason is way more mature than the one she had with Kevin. Jason has his own career and income, and he's infatuated with her. He's lost without Britney when they're apart."
They continued: "She wants a white wedding and to wear something very different from her previous weddings. She's never really had that properly.
"She'd be happy with just a few family members and close friends. Something intimate. She's also thought about a secret beach wedding with a small party afterwards for their families."
Of Britney's father Jamie's opinion about a potential wedding, another insider added: "He thinks Jason is a great guy and much more suitable for Britney than Kevin ever was.
"Ideally though, he'd like Britney to continue dating Jason for the moment rather than jump into marriage again."
