On the back of that exciting day, Brad and Jen have now told friends they're ready for their new lives together and have begun readily planning for a new arrival!
'Everyone was stunned, but absolutely delighted by the happy announcement,' a friend dished to the US publication.
A second source close to Brad told OK! that Jane, Brad's mum, is 'over the moon' about the happy news.
'She has always adored Jen and secretly hoped they would find their way back to each other one day,' says the insider.
'She's overjoyed and can't wait to see them start a family together.'
'It really is a dream come true', another insider dished.
'They are excited and determined to make this happen.'
Some friends even think the actress is already pregnant!
'Some people close to them believe Jen is pregnant,' an insider told In Touch.
This news comes as no surprise to fans, who recently spotted Jen cradling what appeared to be a growing baby bump in Montreal earlier this month.
'From what I've heard, even though she's 49, it just happened naturally - no IVF or anything,' the source says.
'They're ecstatic!'
