It looks like Courteney Cox isn't the only star who got a playful nickname from Jennifer Aniston.
On Wednesday, the Murder Mystery 2 actress, 54, honored her longtime pal, Sandra Bullock, 59, with a special birthday tribute on her Instagram Story and revealed her nickname for the Oscar winner. In a never-before-seen pic of Bullock, where she sips from a mug with caricatures from The Morning Show, Aniston wrote, “Happy Birthday Sand-a-La!!” Sand-a-La? Definitely creative.
