George Clooney
The ‘Up in the Air’ star, might be all loved up with his human rights lawyer wife Amal, 45, - with who he has six-year-old Alexander and Ella, who they welcomed after their 2014 wedding - but once recalled how you do always need a romantic partner to be happy.
The 62-year-old actor said in 2009: "I've had some absolutely great relationships and some not so great relationships. I've been in some relationships where I've felt terribly alone. Just because you're with someone it doesn't mean you're incredibly happy and complete.”
