Spears is believed to have proposed to Trawick as her global Circus tour neared its end. "Britney simply assumed he'd say yes and she couldn't believe it when he said no," News.com.au quoted a Spears source as telling Confidential.
The insider added: "She was furious and embarrassed and it was going to cause major problems if he stayed around. So she told him to get on the next plane home and he was gone within 24 hours and she's been getting on with things without him."
Spears" pals had earlier said that Trawick was the sort of man "who might tempt her to marry again".
