Britney Spears is considering having a baby with her beau.

Britney has been dating ex-manager Jason Trawick since spring of last year. She has two children from her previous marriage to Kevin Federline, Sean Preston, five, and Jaden James, four, and is eager to add more children to her brood.

Britney has tense history surrounding family and parenting issues involving highly publicised custody battles and mental breakdowns. According to a source, having a child with rumoured fiancée Jason would help her put that period behind her.

"She's always wanted a big family but also wants to prove to herself and to her family she is a good mother,' a source told The Sun. 'She wants another chance to put things right.'

Although it was rumoured that Britney was not willing to have children until she and Jason officially wed, she seems to have changed her mind. Britney and Jason seem enthusiastic about moving forward with family planning.

"Now she's finally had the green light from Jason, she can't wait,' said the source.

Earlier this month Britney talked about how much she enjoys her relationship with Jason. She even commented on how he could possibly be 'The One'.

'We have such a great time together. He makes me laugh, and we are so comfortable being ourselves,' Britney told Us Weekly.
