29, 37, 44?
Well, pop quiz fans... the answer is 44.
But now tell us how old you think she looks.
Hopefully, you reckon 29.
We certainly think Meg's looking good for her age.
She arrived at the National Magazine Awards in the US, without a creased eye or wrinkle in sight.
Maybe it's her make-up, maybe it's her genes... we only know we want some of what she's having.
We were so fascinated by Meg's age-evading that we decided to round up other celebs who are stunning as they hit the big 4-0 and beyond.
