The Hold It Against Me singer is said to have told her close friends she is hoping Tranwick will pop the question
A source told The Sun: 'After all her ups and downs Brit is craving stability - hence her broodiness at the moment - and she just wants to settle down with Jason and do it all again the right way. Now her album is out and her tour is almost sorted she feels like getting married again and having more children is the next step.'
The 29-year-old has already been married twice, once to childhood friend Jason Alexander, who she wed in Las Vegas, and then to backing dancer Kevin Federline, with whom she had sons Sean Preston, five, and Jayden James, four.
