Actress Jennifer Aniston has "more confidence than ever" and says tying the knot with her "best friend" Justin Theroux is the "icing on the cake".

"When it comes to relationships, I'm a late bloomer. But I've learnt from my mistakes, am comfortable in my own skin and have more confidence than ever. In Justin, I have met my best friend - that's the icing on the cake," Aniston was quoted as saying by German magazine TV Direkt, reports femalefirst.co.uk.

"He is kind, honest, and generous and has empathy for other people ... I think that's amazing! The fact that he also has a dry sense of humour is a big plus," she added.

The 46-year-old "The Break-Up" actress says the pair took their time before getting married because they did not need to have the "piece of paper" to prove they are together.

"We weren't in a rush. It's not like we felt any less close to one another just because we didn't have a piece of paper to prove we were together," she said.
