Even though her actual birthday is February 11, Jennifer Aniston is planning a big 40th birthday bash at her new Beverly Hills home on February 7, with pals Sheryl Crow and Courteney Cox among the guests. The reason for the early festivities? According to an insider, right after the party, Jen plans to take off on a romantic getaway — which will last through Valentine’s Day — with boyfriend John Mayer. And with John by her side, 40 may be her best year yet. When asked about her upcoming milestone, Jen recently told France’s Closer magazine, “Everyone’s been asking me if I worry about being nearly 40, but no, not really. These days I’m a lot more serene and I’m ready to embrace a new decade.”
