Plans for Jennifer Aniston's wedding to Justin Theroux are either still under wraps or not yet solidified, but the actress is already preparing to look her best on her big day.

The 43-year-old actress is spending some serious cash to keep her famous glow for her walk down the aisle.

Aniston recently 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.

Another big decision Aniston has made about the wedding is that she will now allow her mother to attend the ceremony. The actress has a rocky relationship with her mom, 76-year-old Nancy Dow, and Dow was also banned from Aniston's nuptials to Brad Pitt in 2000.

"When Nancy started asking a bunch of questions about the upcoming event, it set off an alarm in Jennifer's head," a source said. "She realized her mom was gossiping way too much about her wedding plans."

Aniston reportedly thought her mother would threaten the low-key wedding she's hoping for.

"After her star-studded $1 million wedding to Brad, Jen now wants a much less formal and less publi­cized ceremony," the source said. "And she believes Nancy's loose lips are a threat to her privacy."

But if Aniston has her way, she could very well be walking down the aisle in a maternity wedding dress. Friends have said she is ready to get pregnant with Theroux as soon as possible.

"In truth, she'll be overjoyed whenever it happens; if that means she has to walk down the aisle with a baby bump and do her toasts with apple cider, then so be it," the insider said.
