More Presents En Route to Jennifer Aniston

After an elaborate birthday bash this past weekend, Jennifer Aniston has more surprises in store from best friend Courteney Cox Arquette and daughter Coco.

At last night’s Saks Fifth Avenue Unforgettable Evening event, Cox and Gwyneth Paltrow were honored for their contributions to Women’s Cancer Research. While dashing down the red carpet, Cox was asked by reporters if she or her daughter with David Arquette had gotten gifts for Aniston’s birthday (today!).

“I can’t say yet,” Cox yelled as she was whisked into the grand dining room at the Regent Beverly Wilshire Hotel in Beverly Hills, California.

Obviously she and little Coco must be sitting on some sweet gifts for 40-year-old Jen, who celebrated the milestone birthday over the weekend with a bash at her Los Angeles home with John Mayer, Cox and Arquette, Sheryl Crow and Tobey Maguire (who attended wwith wife Jen Meyer).

No word on a day-of celebration, though it’s possible Aniston could hit her longtime favorite The Sunset Tower Hotel’s Tower Bar. Or perhaps she’ll host a more intimate celebration, followed up with a little sleepover?
