CARRIE FISHER HAD AN 'INTENSE' AFFAIR WITH MARRIED HARRISON FORD
People speculated for years the on-screen Star Wars lovers were more than friends in real life and 40 years on, Fisher has finally confessed to their "intense" three-month affair.
Now 60, the actor' new memoir The Princess Diaristis a collection of the diaries she kept while filming the original 1976 Star Wars.
Speaking to People, Fisher said their whirlwind romance was "so intense" and despite being "so inexperienced ... I trusted something about him. He was kind."
Describing it as "a very long one-night stand" Fisher added "It was Han and Leia during the week, and Carrie and Harrison during the weekend."
The New York Times best-selling author's 2006 memoir was all about self-discovery and reinvention and Gilbert's personal life this year seems to simply be another chapter.
Less than two months after the announcement she was separating from her husband José Nunes, Gilbert took to Facebook to come out and reveal she'd fallen in love with her female best friend Rayya Elias.
In a Facebook post entitled 'ME AND RAYYA', the author details how it was Rayya's diagnosis with cancer that helped her realise she was in love with the Syrian author.
CHARMED STAR ROSE MCGOWAN WAS RAPED
After Trump's infamous 'grab her by the p*ssy video surfaced, the #whywomendontreport went viral on Twitter.
One woman who chose to tell her story was Charmed actor Rose McGowan who revealed she had been raped by a studio head.
Never one to succumb to Hollywood pressures to be thin, Wilson actually revealed she gained weight to make it in showbiz.
The 36-year old actress reminisced withThe Telegraph back in July of a time she acted next to a girl who was bigger than her.
"I was like: 'Oh. That girl's getting a lot of laughs, a lot easier than me. What is it?' Because I don't think there's much difference in talent. And I remember distinctly thinking: 'I think it's because she's fatter'.
Wilson wondered at the time if she was fatter, perhaps she'd get more laughs "and then suddenly, I was fatter, and doing comedy."
Her small role in Bridesmaids five years ago propelled made her a global star with Rebel believing it was her size that gave her the edge.
"I saw my size as being an advantage," she says, "whereas so many women see it as a disadvantage".
THE ENTIRE KIM/KANYE/TAYLOR FEUD
2016 was a big year in the Taylor vs. Kanye war. Starting back in 2009 with Kanye's now iconic "I'mma let you finish, but..."
The biggest development in their angry feud came in February when West debuted his new track 'Famous' which included the lyrics "I feel like me and Taylor might have sex. Why? I made that b*tch famous."
Plenty trashed the rapper over the incident but Kanye hit back on Twitter claiming "I called Taylor and had an hour long convo with her about the line and she thought it was funny and gave her blessings."
Taylor's camp said she was unaware of the actual lyric calling her a b*tch but then Kim claimed in a June GQ interview she had video footage of Swift approving the song.
"And then they sent an attorney's letter like 'Don't you dare do anything with that footage,' and asking us to destroy it," Kardashian said.
Kim released the video and Taylor, completely done with the feud took to Instagram to slam the couple.
Each reveal in that feud had our heads spinning and it doesn't seem to be cooling down any time soon.
LEY CUOCO REVEALS PLASTIC SURGERY WAS THE BEST THING SHE EVER DID
One of the highest paid TV actresses in history and current star of The Big Bang Theory, Cuoco revealed last month she owes a lot of her success to something most wouldn't expect - plastic surgery.
The 31-year old sat down with the magazine Women's Health and said she has nothing to hide about her past with body modifications.
"Years ago I had my nose done," Cuoco shared openly. "And my boobs - best thing I ever did. Recently, I had a filler in a line in my neck I've had since I was 12. As much as you want to love your inner self ... I'm sorry, you also want to look good."
While the TV star got candid about plastic surgery, she also insisted it should be something people do for themselves, and only themselves.
"If it makes you feel confident, that's amazing," she said.
EVERYONE'S IN THE MILE HIGH CLUB
When it comes to Ellen's popular 'Never Have I Ever' segment, the TV personality seems to have a favourite question.
Considering plenty of celebs's preferred mode of travel is first class or even private jets, DeGeneres loves asking the rich and famous if they're a part of the mile high club.
This year alone stars like Jennifer Lopez, Jane Fonda and Ellen DeGeneres have all admitted to having plane sex while last year Ellen's segment outed Gwyneth Paltrow, Johnny Depp, Kris Jenner and Miranda Kerr to name a few.
Fonda admitted to joining the daring club and backed it up with a hilarious story.
"I was 50 years old, it was my fourth date with Ted Turner," the Monster in Law star begins.
"He has his own plane and we get on the plane and he says, are you a member of the Mile High Club and I didn't know what he was talking about," she laughs.
"So, I joined," she says to the audience's delight.
