What had ET readers buzzing this week?
Entertainment Tonight's Christina McLarty was the first to catch up with Kim Kardashian in Las Vegas at her first appearance since her boyfriend, rap star Kanye West, announced that they are expecting a child together
Kardashian tells ET that pregnancy is harder than she imagined and the changes to her body are difficult. She also tells McLarty that she is taking a lot of naps.
"I wouldn't say it's been easy," she said. "When people say that pregnancy is fun and they love it I would have to disagree. ... Even my sister has made it look easy, but it's not as easy as people think. ... I heard it's all worth it so I'm looking forward to that."
Kardashian hosted a New Year's Eve event at 1OAK Nightclub at The Mirage.
From Beyonce to Demi Lovato, see how big celebrities celebrated their New Year's here
Taylor Swift and Harry Styles had equally amazing 2012's, and they kissed good-bye to the preceding 365 days together in Times Square.
After singing on ABC's New Year's Rocking Eve, Swift and Styles braved the crowds to watch the ball drop. And to the hordes of fans who'd gathered to count down to midnight, "Haylor's" ensuing smooch ended up being more captivating than all the twinkling lights in the sky.
Though Julianne Hough is known for her bubbly personality, it turns out not everything in her life has been so charmed.
Julianne covers Cosmopolitan's February issue, where she reveals she suffered mental and physical abuse while living in London as a young girl in order to pursue her dancing career. She attended the prestigious Italia Conti Academy of Arts on a five-year scholarship, along with her brother Derek.
"While I was in London, I was abused, mentally, physically, everything," she reveals, and it didn't stop there -- she says it got worse when she "started hitting puberty, when I started becoming a woman and stopped being a little girl."
Though Julianne declines to go into the specific details, she does say that she was forced to push out an overly sexual image at a very young age.
"I was 10 years old looking like I was 28, being a very sensual dancer. I was a tormented little kid who had to put on this sexy facade because that was my job and my life. But my heart was the same, and I was this innocent little girl. I wanted so much love," she says. "I was told if I ever went back to the United States, three things were going to happen. One: I was going to amount to nothing. Two: I was going to work at Whataburger. And three: I was going to end up a slut. So, it was like, I can't go back. I have to be this person."
Julianne of course did return to the United States, where she became a star thanks to her winning performances on Dancing with the Stars.
On a lighter note, Julianne also dishes to the magazine about her relationship with Ryan Seacrest.
"We love what we do. We take pride in giving it our all, but then when we're alone, we really focus in on going to dinners and being extra-romantic and affectionate and just being there for each other," she says.
And clearly, the two know how to keep the sparks alive -- Julianne recalls when the two were stranded and alone during Superstorm Sandy in New York, and took advantage of the rare time the two workaholics couldn't work.
"It was great," says Hough, smiling. "We put on some candles, had some sexy time....Ha!"
Rihanna faced a bit of backlash from her Instagram followers after posting a pic of what looks to be marijuana.
The S&M singer, 24, captioned the abstract pic, writing: "This nug look like a skull or am I just....?"
With nearly 6,000 comments to the pic and over 9,300 likes, with one reader responding: "Why r u teaching other girls who look up to you to do this?"
Hours later, Rihanna posted another message that read: "I don't really give a f***."
