Jennifer Aniston will still be wearing a bikini when she's 80.

The 46-year-old actress doesn't think people should tone things down as they get older and doesn't see why people are concerned about what others look like.

She said: "If I can be the first 80 year old to go out there successfully in a bikini, then I'll take that on.

"I don't think anybody needs to rein in anything because of an age. That is absolute BS. To each his own! Everybody needs to stay in his own backyard."

Jennifer turns 47 next month but she jokingly claimed she is planning to ignore the big day.

She told People magazine: "Is my birthday happening soon? Oh, that's ridiculous. It's too soon for that. I'm going to pass this year.

"I might just quietly celebrate. But I do love any excuse for a party!"

Last year, the 'Cake' star married long-term partner Justin Theroux and couldn't be happier.

She said: "[Married life] is awesome. I love it!"

It was recently revealed Jennifer honed her physique with martial arts sessions with her husband.

A source previously said: "They've become great sparring partners.

"Jen's been into Budokon for years, and she and Courteney [Cox] used to do classes with well-respected martial arts teacher Cameron Shayne.

"Jen swears by it for upper body strength and cardio - and Justin's really into it now, too.

"It's fast becoming an obsession for them."
