The 44-year-old actress is keen to tie the knot with her fiance Justin Theroux in a low-key ceremony at their mansion in Bel Air, California, and is planning to give her biker sibling Alex one of the lead roles on her big day, reported Us magazine.
Alex, who is also known as AJ, often drifts between Los Angeles and Alaska in his van and has 'Live Free' tattooed across his chest in addition to a number of other inkings plastered across his body.
"AJ is exactly the kind of person that security would throw out of Jen's wedding. Instead he'll be front and centre at the ceremony," a source said.
Aniston previously married Hollywood hunk Brad Pitt, who is now engaged to Angelina Jolie, in a lavish ceremony in Malibu in July 2000, but is keen to venture in a different direction this time around.
"Jen hated her wedding to Brad Pitt. It was too big and incredibly stressful. This time she wants a small family affair and she wants to go the extra mile to let her father see that she is still happy at last. And she knows that including his son would make him happiest," the source said.
