The 'How I Met Your Mother' star couldn't be much more than 30 right? Wrong! The mum of 2 will be 40 next year.

We were shocked to discover that the TV star is 51. And he's still as gorgeous as ever...think we need to pass on his skincare tips to our hubbies

Looks like the key to keeping your youthful good looks is yo-yo dieting...or at least it hasn't done Kirstie any harm. The actress turned 62 in January! While we suspect she might have had a little 'help' she still amazing.
