Just like any other bride to be, Jennifer Aniston is concerned with looking her very best on her big day.

But unlike the average bride, Aniston has the resources to experiment with different treatments and procedures to ensure that she looks perfect when she marries fiance Justin Theroux.

Her latest concern is her breasts, according to a new report from British magazine Look. The 43-year-old actress has been indulging in a particular kind of massage therapy that targets the breasts and works to keep their shape and pertness, a friend of Aniston's revealed.

"Her massage therapist insists this technique helps maintain shape and prevents sagging," a source told the magazine. "Jen's been having the massages for 12 weeks now — she started as soon as she got engaged and says they're the best treatment she's ever had."

Aniston wants to look her absolute best on her wedding day, and since she has been pleased with the massage treatments over the last few months she intends to continue until she gets married.

"Jen wants to be in the best shape of her life for her wedding," the insider said. "She's making sure her boobs look their best as she knows they're one of Justin's favorite parts of her body."

And the specialized massage therapy isn't the only pricy health treatment Aniston has taken up to prepare for her nuptials. In September of this year, just more than a month after Theroux popped the question, Aniston spent $2,000 on a customized skin rejuvenation treatment at the Mila Moursi Skin Care center in Beverly Hills, according to reports.

The luxurious facial treatment lasts an hour and a half, and it's a favorite of Hollywood's biggest stars.

"Our leading ladies like to get the treatment," a source said. "Jen's been a regular at Mila Moursi since August, when she got engaged."

The Mila Moursi website lists the customizable rejuvenation treatment with a price tag that starts at $1,850.

"Our exclusive method has been proven to minimize the aging process, nourish and rejuvenate devitalized or sun-damaged skin, help lift and contour the face. Regular treatments reduce the appearance of fine lines and wrinkles, and help maintain a firm, glowing skin," the website description says.
