There is a HUGE variation in how women (and men) look for their age.
I am (not boasting) often queried about my age because I am over 60 and have concessions for entry to places. Once I was in a queue and it was quite embarrassing as the asst thought I was asking for concessions for my children.
So, I can be judged as around 45 even though I am early 60s.
There are some women who have fixed concepts of what 50 or 60 looks like.
You've got to acknowledge that people who make a living from being on TV will have help.
-Usually, they are pretty to start with (which is why they got the telly job in the first place.)
-They take care of their appearances.
-They have help from hairdressers, stylists, cosmetic drs, (fillers, Botox, all the stuff that is out there) dentists etc.
I've looked at lots of photos of Tess after reading this thread.
I reckon she has had lip fillers, teeth whitening and maybe more.
However, if you look at photos of her where she's not made up for TV shows, she looks her age. She has a lot of lines around her eyes and her cheeks are very lined at the sides when she's smiling. She looks like someone of 52 who invests a lot in grooming, has a pretty face, and is tall.
