The actresses snubbed Thanksgiving celebrations in the U.S. to walk the red carpet in Marrakesh for the re-opening of Hotel La Mamounia, along with Pirates of the Caribbean star Orlando Bloom.

But it wasn't all glitz and glamour for Paltrow - she was quietly mourning the loss of her father, Bruce, who would have turned 66 on Thursday. He lost his battle with cancer in 2002.

The Shakespeare in Love star wrote in her Goop.com newsletter, "I dedicate this Thanksgiving letter, on parental acceptance, to my father, who would have been 66 today. He was the greatest parent, friend, rabbi any girl could ever have asked for. Happy Birthday Bruce. And Happy Thanksgiving everybody."

Paltrow split from fiance Pitt in 1997 after dating for two years, while Aniston ended her five-year marriage to the actor in 2005.
