Jennifer Aniston says people shouldn't be afraid of being single.

The former 'Friends' star - who was previously married to Brad Pitt - thinks too many people settle for someone just because they are afraid of being alone.

She said: "I think it's about really finding that person that means something and not settling. There are a lot of single people who are as happy as a lark. There are a lot of married people not as thrilled as they would like to be."

The 41-year-old actress plays a woman who gets pregnant using a sperm donor in new movie 'The Switch' and she chose the role because she can "relate" to it.

She explained to "I relate to all women that I know that have gone through this choice, this decision in life. Especially in this case, the women in my life who have gone through the struggles and heartbreak and frustration of fertility and adoption and all of that. I think that's why it jumped out at me so immediately, the connection I had to it."
