(showbizspy.com) - Jennifer Aniston is set to marry boyfriend John Mayer this fall, according to reports.
The former Friends actress is said to be keen to marry the No Such Thing hitmaker before she turns 40 next year.
A source tells OK! magazine, "She's at an age where she is thinking with her head not just her heart.
"No way would she still be with anyone if marriage wasn't a real option."
When Aniston married Brad Pitt eight years ago, the couple forked out a whopping $1 million on the ceremony, which featured a gospel choir; four bands; fireworks; and an estimated 50,000 flowers.
But this time, Jennifer is said to be opting for something more low-key. "She doesn't want anything elaborate or showy," the source said.
Friends say with the pair sharing a similar outlook on life, Jen and John, 30, are made for each other.
"They are just a perfect match," says a friend. "And everything about that will come through in this beautiful wedding."
Jennifer was married to Pitt for five years. They separated in 2005 amid allegations the Fight Club actor was cheating on her with actress Angelina Jolie, with who he now has six children. The media also speculated that the split was due to Aniston's refusal to have children. However, Jennifer denied the reports.
In a 2005 interview with Vanity Fair magazine, she said, "I've never in my life said I didn't want to have children... I've always wanted to have children, and I would never give up that experience for a career."
Mayer, 30, has dated a string of famous women over the past few years, including Jennifer Love Hewitt and Jessica Simpson.
