'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.
A source adds, 'Brad and Jen were so eager to wed again, they just had a private unofficial ceremony in the backyard of his house in the Pacific Palisades.'
'The home overlooks the coastline and isn't far from the beach - it's breathtaking. It was the perfect setting.'
In Touch reports the former couple recommitted to each other on a sunny, blue-sky afternoon ahead of their original wedding anniversary on July 29.
Brad's parents, his six children, and a few famous friends were also in attendance, the publication claims.
Among the famous faces were Jen and Brad's close friends, George and Amal Clooney and Courtney Cox, who acted in the bridal party.
'There wasn's a lot of formality,' says the source. 'Just a beaming Brad and Jen pledging their love to each other.'
No one is happier than Brad's parents, Bill and Jane, In Touch's report adds.
'Jane truly considers it a blessed event,' the insider spills. 'She's always had a special kinship with Jen and was instrumental in her getting back together with Brad.'
An insider has previously stated that ever since Jen and Justin's split earlier this year, Jane has been begging her son to marry Jen.
'Jane always preferred Jen to Angelina,' the Pitt insider claimed.
In the last 18 months, Brad's devoted himself to a sober lifestyle and started therapy, which insiders say has paved the way for his renewed relationship with Jen.
'Brad and Jen are more open with each other now than they ever were in their marriage. They are older, wiser and different people in different places of their lives now,' says an insider.
'They both know they got it wrong the first time around.'
Jen is finally getting the happy ever after she's longed for.
'She's in it for the long haul with Brad,' a friend tells In Touch. 'Brad loves how they've both come full circle and found each other again. They were destined to be together.'
Neither Brad or Jen have responded to In Touch's report.
