My best guess is that Ms. Turner is somewhere north of 45 in this video, as it would be after the release of here 1984 mega hit album Private Dancer, which featured this song, the proper video of which is here. She appeared with Beyonce last year.
the cover - Danielle may not be able to rock the high heels like Tina, but check her out without those glasses!
and what is Tina Turner doing nowadays you ask - well, she toured last year. We should all look and sound so good at 68.
