0 Miley Cyrus wants a bun in her oven rather quickly

She may be hitting the gym like a crazy person these days- and has the body to show it- but Miley Cyrus is willing to give it all up for a baby.

"Miley and Liam really want to have a baby quickly," a source close to the Cyrus family told US magazine. "They are both mature and ready for this. Miley is 19 going on 40."

And it seems that Miley's fiancé, actor Liam Hemsworth is all for starting a family with his bride-to-be, while they are still spring chickens, with friends of the couple revealing the 22-year-old heartthrob has been the main instigator in Miley's pregnancy plan. 

But while Miley may be set to move from the A-List to B-List - of the Baby kind that is- judging by the singers recent tweet, something tells us that anything to do with this bub-to-be will be shrouded in secrecy. 

"How is it legal for men I've never seen before to sit in front of my house and then follow me around! So shady and scary," tweeted the songstress only a few hours ago. 

Ouch!
