Unless she turned 60 today, 60+ is representative of her age. She is older than 60 years old. The + is indicating its past her 60th birthday, which it is.
Geeezus, never seen so much bitching over a year in age, WTF? She is one of the very best and still knocks it out of the park, her images are usually taken the same day. So see her or don't see her but move on.
