We all know that Jennifer Aniston and Courteney Cox are BFFs, that Jay-Z and Kanye West are tight and that Drew Barrymore and Cameron Diaz's friendship extends beyond Charlie's Angels.

But, here are a few that maybe aren't so obvious—we've graded them for you on a Surprise Factor scale as follows;

Surprise Factor Scale;

  1. Not at all surprising, tell us something we don't know
  2. A little surprising, but they're in the same business so not so much
  3. Hmm takes some thinking about but kinda cool
  4. Really?  Wow I would never have though that
  5. Say what???!!!  How do these two even know each other?  What do they have in common??

 

Remember that saying there’s no such thing as bad publicity? Well that’s not true if you’re a charity and you want someone to front your campaign.

For many non-profits, controversial stars like Chris Brown, Naomi Campbell, Lindsay Lohan and Lance Armstrong need not apply.

According to The Hollywood Reporter, philanthropy executives and people who match stars with charitable causes have actually turned away some stars wanting to lend their services to help better the world – or in some cases, improve their public image.

One expert explains:

"You have to be appreciative and you can't say, 'Thank you for your interest, but there's no way in hell’.

“It has to be a much softer dismissal."

Presumably that’s what many non-profits told Breezy when his team allegedly approached several high-profile charities in a bid to clean up his image following his 2009 arrest for beating up Rihanna.

Seems mug shots are a no-no in this field.

According to Shawn Sachs—whose firm Sunshine Sachs represents charities like the Bill & Melinda Gates Foundation.

He says:

“If someone is taking mug shots and they’ve been associated with your brand, you will reap some of that bad [press] too.”

Just because you started the charity doesn’t make you immune either. Armstrong was ditched from his own charity, Livestrong Foundation, after his doping scandal led to him being stripped of his Tour de France titles.

Doing something that completely goes against the principles a charity represents is also a cardinal sin in the philanthropic world.

So, as you can probably imagine, Naomi Campbell strutting around in a sable coat, just after she said she’d rather go naked than drape herself in fur, didn’t sit well with PETA.

The animal rights organization’s senior vice president of communications, Lisa Lange, tells the Reporter: “We fired her for wearing fur.”

As for everybody's favorite serial liar, LiLo, in 2009 she was accused of exaggerating the success of her work after partnering with a non-profit to film a BBC documentary about child trafficking in India.

The actress tweeted just 24 hours after setting foot in the country: “Over 40 children saved so far…”

And when it comes to reality TV stars, they’ll wait a long time for Lara Shriftman at the PR firm Harrison & Shriftman to call on their services.

She says:

“I look for people who are really, really behind an issue and are working for the cause.

“Not someone who is just looking to get publicity for publicity’s sake.”

All those Real Housewives better get to the back of the line!

Sheryl Crow has a history of dating famous men, but she isn't exactly without regret when it comes to her romantic life.

According to the 52-year-old singer, she would love to get married - but will never settle.

"Hey, I would love to get married – I'm still old-fashioned. But I don't think marriage is the be-all-and-end-all," she told Good Housekeeping. "It's better to have three broken engagements than three divorces."

Sheryl has been famously linked to celebrities such as Owen Wilson, Eric Clapton and Lance Armstrong. Although she made the choice to be with these men, in hindsight the musician thinks she always put herself in second place.

"I have always gone out with guys who were highly successful, which would seem like it would put me at an equal level," she said. "But what ends up happening is that one of you becomes smaller – and it was always me. … I do think that sometimes in order for one person's light to shine, everyone else has to dim theirs."

I think we can all agree that one) Sheryl could take her pick of men and two) Lance Armstrong was a bullet DODGED.

 

Ouch… just ouch!!

Lance Armstrong endured a very cringe-worthy moment indeed during a recent game of Cards Against Humanity.

You can only imagine how awkward it could have been after the 42-year-old drew the answer card “Lance Armstrong’s missing testicle” —however, proving he does have a sense of humor, the disgraced cyclist Tweeted the incident out to his followers.

“Just another night of playing Cards Against Humanity…” he captioned a photo of the offending card, although, he chose not to share what question cards, if any, were played against it.

Armstrong is a cancer survivor, having been diagnosed with testicular cancer in 1996 that spread to his lung, lymph nodes and brain—he subsequently had a testicle removed and went on to start the Livestrong Foundation, which aims to “unite, inspire and empower people affected by cancer.”

He resigned his position as the foundation's leader in 2012 after his doping scandal went public.
