Jennifer Aniston has surprising reaction to one of the most bizarre rumours ever written about her

Jennifer Aniston finally confronted one bizarre rumour about herself that has circulated over the years.

The 55-year-old Friends star recently appeared on Jimmy Kimmel Live! and played a game where she clarified whether some things were fact or fiction.

Host Jimmy Kimmel and Aniston rattled through a series of headlines about her after he showed the actor a copy of InTouch magazine from August.

Next to a photo of Aniston and former US president Barack Obama, the headline read: "The Truth About Jen And Barack."

The subheading read: "Michelle betrayed as Aniston steals her husband's attention."

Aniston then explained how she felt when being briefed on the story.

She said: "Of all the calls you get from your publicist where you’re just like, ‘Oh no, what’s it going to be?’, or the email saying, ‘Some cheesy tabloid is going to make up a story’… and then it’s that. I was not mad at it."

The star clarified: "That is absolutely untrue."

Aniston said she'd met Obama once - but 'knows Michelle more'.

Kimmel then took the opportunity to address more headlines regarding Aniston.

She laughed: "Oh good, we’re going to dispel rumours, I love this."

In case you were wondering, it's untrue that she ever had a '$4,000 anti-aging water filter' for her dogs at home, and she also never had a 'black belt in jujitsu'.

But of course, a broken clock is right twice a day - and as a result, some headlines turned out to be true.

Aniston loves to unwind by way of a salmon sperm facial, she takes jars of olives abroad when she travels, and she was asked for a selfie while in the buff at a sauna.

Kimmel also confronted Aniston about rumours she kept her 'dead therapists ashes' in a a zip-loc bag.

Aniston said: “Can I plead the [fifth]? That’s a little true… I’m going to sound like I really need a therapist after this."

Kimmel interjected: "Sounds like you need one one way or the other."

In a 2012 interview with GQ, Aniston had admitted she carried round her late therapist's ashes.

She said: "I have my therapist ['s ashes] in a bag. She thought of me sort of like a daughter, and I thought of her sort of like a mum. I went to her funeral. They split her up into little Ziploc bags they handed out like party favours."

It also transpired that belly dancing is somewhat of a Christmas tradition, after Kimmel asked if it was true she had to do it every Christmas Eve.

Aniston opened up: "No just Christmas Eve. [It was] like when you say to your child, ‘Play piano for everyone,’ or, ‘Let’s sing for everyone’.

"I get such anxiety when my friends do that to their children, because I have inner trauma from having to perform and belly dance for my Greek aunts and uncles and grandmothers. I get it."
