Leave it up to Oprah to ask all the tough questions!

During her sit down with the whole Kardashian clan for an interview on Oprah's Next Chapter, the talk show host asked the 31-year-old reality star if she credits her infamous sex tape for launching her career.

"Would you be where you are had there not been a sex tape?" she asks, to which Kardashian responds, "You know, I think that's how I was definitely introduced to the world. It was a negative way, so I felt like I really had to work ten times harder to get people to see the real me," she explained.

Adds her mother Kris Jenner: "No mother ever wants to hear something like that. I could tell she was in a lot of pain."

No subject was off-limits, with Kim discussing her failed 72-day marriage to NBA player Kris Humphries, her relationship with new boyfriend Kanye West, and the lessons she's learned living life in the spotlight.

We have to give it to Miss Kardashian - she's a PR pro!

Carly Rae Jespen, Justin Bieber's new protege, showed that she had what it takes to hang with the Katy Perrys of the world as the young singer won big at the 2012 MuchMusic Video Awards!

The Canadian singer, who's signed to Bieber and his manager Scooter Braun, won three awards, including one for her breakout hit Call Me Maybe.

On Saturday Britney Spears and Demi Lovato were in Oakland, California for yet another round of auditions for The X Factor, and the ladies were joined by fellow judges Simon Cowell and L.A. Reid.

Demi loved the attention, but Brit Brit seemed a bit overwhelmed! The pop star plugged up her ears and made a series of silly faces from the stage, but despite the din inside the Oracle Arena, she had a blast. "Another fun day of judging w/ @SimonCowell @ddlovato @LA_Reid," she tweeted. "The audience was so sweet! I hope tmrw's talent is ready to wow us all...."

Demi also shared her sentiments on the microblogging site, but she seems more interested in herself than the contestants! Demi tweeted this shot and wrote, "Loving my pink hair and obsessed with my new Topshop outfit and Chloe Green shoes!!!!"

Jack Osbourne has been diagnosed with multiple sclerosis, an insider confirms to Us Weekly.

"Thank you all so much for the kind and inspirational words," Osbourne, 26, tweeted late Sunday. "It means a lot. #adaptandovercome."

A source tells the mag, "He knew something was wrong for awhile. Everyone is sad, but he is being strong about it."

The disease affects the central nervous system, and it can cause problems with muscle control, vision, balance, and thinking. MS is unpredictable and symptoms vary from person to person, and according to the National MS Society, approximately 400,000 Americans suffer from the disease, with 200 more being diagnosed each week.

This sad news comes just two weeks after Jack and fiancee Lisa Stelly welcomed their first child, a daughter named Pearl.

Break out the blue!

Giuliana and Bill Rancic hosted a baby shower in LA yesterday afternoon, and revealed they are expecting a son via gestational surrogate. The couple's shower invite read "Blue or pink, what do you think?" and guests were kept guessing until the happy couple revealed the gender of their unborn baby.

It's been a long road to starting a family for the E! News host and her hubby, who struggled for years to conceive before turning to surrogacy. They announced the happy news in April, just months after Giuliana underwent a double mastectomy due to a breast cancer diagnosis.

Congrats to the soon-to-be parents!

After her health scare at the Ritz-Carlton Marina del Rey on Friday morning, Lindsay Lohan caught up on her rest this weekend at the Chateau Marmont.

After sleeping all day Saturday, we spotted her on a hotel balcony around 7pm looking puffy and bloated, with a minor case of bed head.

And this morning, Lindsay's already on back on the set and back to work. We hope those extra hours of sleep pay off!

Bad news for Tom Cruise!

Despite the hype surrounding Rock of Ages, the big screen adaption of the '80s Broadway rock musical took the number three spot and a paltry $15.1 million at the weekend box office.

Madagascar 3: Europe's Most Wanted held on to the top spot with $35.5 million, and Prometheus stayed snagged the number two spot with $20.2 million.

Cruise's flick wasn't the only flop this weekend. The Adam Sandler comedy That's My Boy grossed $13 million, which marks the actor's worst opening for a comedy in eight years. Yikes!





These two "friends" are still hanging out and spending LOTS of time together, according to our photographer ...

One of our shooters saw Mila Kunis arrive at Ashton Kutcher's house Friday afternoon and didn't see either emerge until today, when they shared a ride on Ashton's motorcycle!

After the ride, Mila grabbed a coffee and smoothed her helmet hair. Not even a helmet can ruin this girl's good looks and we think Ashton's taken notice!
