Jennifer Aniston may have split up with John Mayer but that isn't going to stop her from forging ahead with her baby plans, according to a new report.

The actress - who supposedly dumped John over his obsession with micro-blogging site Twitter - is reportedly researching alternative ways to falling pregnant as soon as possible.

A source tells Life & Syle, "She's working out how she wants to proceed. But one thing is definite: She wants a baby, and she wants one soon.

"Yes, she was hoping to have a baby with John. But I think deep down she knew he probably wasn't ready to settle down and start a family.

"She knows the one luxury she doesn't have right now is time. She's willing to become a single mother."

Jen and John's tumultuous relationship lasted one year, with a brief split in the middle, and it was after the couple went public with their relationship at the Oscars last month that the pair went their separate ways - but will it be for good this time?
