Ever since Jennifer Aniston’s idyllic-seeming marriage to Brad Pitt ended in 2004 -- permanently adding the term "Brangelina" to our vocabulary -- tabloids have tried pairing her with other celebs. But despite short-lived affairs (with, most notably, Vince Vaughn and John Mayer), she remains stubbornly unattached. And she likes it that way! Aniston, 40, told Oprah in 2005 that living alone was "pretty fantastic," and in a 2009 Daily Mirror interview, she said she was thriving: "I have a really great relationship with myself and that's a lifelong process. I have a great job, a great family and great friends. I have my health and I do what I love to do." The star even renovated her bathroom to accomodate guy-free pampering!
