It looks like it hasn't been a very good month for Jennifer Aniston. Rumor has it that the Hollywood actress has not only been jealous of Angelina Jolie's Maleficent success at the box office, but that she's also envious of her brother AJ who is set to tie the knot and extend his family real soon, too.

Is Jennifer Aniston Jealous Of Angelina Jolie Again?

Radar Online reports that Aniston's half brother AJ is reportedly expecting his first child with makeup artist Adriane Hallek. The couple announced back in January that they are planning on trying the knot and now Hallek has allegedly been spotted holding an ultrasound in her hand after leaving a Los Angeles-area medical clinic.

In addition to AJ's baby news, it also seems as though Aniston is getting pressured by her father to get pregnant as well. The elder Aniston is worried that he might not have enough time to enjoy his grandchildren if his daughter delays her pregnancy plans any more.

"Jen's dad... knows that if she doesn't hurry up and get hitched, he might not live long enough to see her kids," the source says of the 80-year-old actor. "He's anxious to see his grandchildren before it's too late."

"It would be ironic if AJ makes his dad a grandfather before his sister Jennifer does," the insider added. "I don't think anyone is expecting that!"

Aniston and Theroux are rumored to be tying the knot on August 10, which is also his 43rd birthday. The couple is planning a low-key ceremony with only their closest family and friends invited to the affair.
