Harry Styles, Zayn Malik, Louis Tomlinson, Niall Horan and Liam Payne waved hello to fans outside their hotel in Milan yesterday, and this was after the boys gave a stellar performance on Italy’s X Factor at Assago's Forum.

Louis tweeted, "Italy ! Wasssaaaappppppppppp ... You guys really have been so amazing over these few weeks :) loads of love :)," but then he added, "Not having coco pops on room service is a crime!!"

One Direction recently wrapped up their Take Me Home world tour, but seeing as they dropped their new album Midnight Memories last month, it seems like there should be a new tour announcement coming soon.

Reese Witherspoon is getting fit! The Oscar winner was once again spotted after her grueling workout at Burn 60 on Thursday in Brentwood, Calif. And we gotta admit -- the 37-year-old is looking damn good!

Wearing a long-sleeved black shirt, black leggings and colorful kicks, Reese was looking oh-so-sporty for her trip to the gym.

We gotta hand it to Reese -- she really seems to be dedicated to working out! The actress has a couple projects in the works, so it's not surprising she's trying to stay in tip top shape for the big screen! The 37-year-old just wrapped Wild, a film based on Cheryl Strayed's 2012 memoir about her 1,100-mile solo hike. She's also set to begin shooting The Intern alongside Robert De Niro.

The mom of three has been hitting Burn 60 in Brentwood on the reg for the past few months. We aren't sure if it's because she is exercising for a role in one of her upcoming films, or if she just got inspired after pics of her bum were splashed all over the Internet when photogs caught the Oscar winner accidentally flashing her backside in June. Maybe that's just what the star needed to kick her butt into gear!

The 37-year-old made headlines when she debuted her slimmer bod at the Devil's Knot premiere during the Toronto International Film Festival in September.

Devil's Knot, which hits theaters in 2014, is based on the true story of three teenagers who were falsely convicted of killing two 8-year-old boys in Tennessee. The trio, known as the West Memphis 3, were released two years ago after spending 18 years behind bars. Reese plays Pam Hobbs, the mother of victim Stevie Branch, and Colin Firth also stars in the movie as Ronald Lax, a private investigator who represented one of the accused teens.

Khloe Kardashian is reportedly filing for divorce today from estranged hubby Lamar Odom, but when X17 photographers caught the reality starlet on the way to the gym this morning, she had no comment on the news. Khloe was not wearing her wedding or engagement rings, but this isn't exactly a surprise, seeing as it's been nearly two weeks since we've seen her wearing either of the baubles.

Apparently the bizarre video of Lamar rapping about cheating on Khloe was what pushed her over the edge, and as soon as the clip was posted online, she stopped wearing the rings. That was back in November when Khloe was on a business trip in Australia.

Khloe is reportedly citing irreconcilable differences, and we're guessing she will have her lawyer handle it and lay low at home. So far we have yet to receive confirmation that the paperwork has been filed...

A fresh faced Cameron Diaz beamed when she proudly showed off the cover of her new self-help book The Body Book. The 41-year-old shared the pic via Twitter on Wednesday, in which she holds the book tightly to her chest -- blue eyes starring at the camera. We love that Cameron wrote a body book, because everyone knows she has one of the best bods in Hollywood -- and we also love that Charlie's Angels actress was totally makeup free for the beaming pic!

Along with the pic, "One of my proudest moments! Receiving the first bound copy of The Body Book!! @thebodybook LADIES!! I wrote this book for YOU and YOUR BODY.. And I'm so excited to share it with you!! You can pre-order it now. http://amzn.to/1cmXmY6 #loveyouramazingbody"

A publishing source told E! News that the leggy blonde considers the book an act of giving back, and that, "She wants to stop their fixation on being thin, and for teenage girls to understand that being healthy is more important."

And while health is very important to actress, the book isn't about fad diets or all about Cameron.

"This book isn't about her,' the source said. "And it's not a diet of any kind. Of course, it's her own journey that has helped her realize what's important, but she wants the book to appeal to everyone, and not just be about her own food choices."

The book also features advice from some of the movie star's celeb pals like Drew Barrymore, Jennifer Lopez and Gwyneth Paltrow.

Cameron is currently in the middle of filming her latest movie, Annie, in which she takes on the role of Miss Hannigan, originally played by Miss Hannigan, in the remake of beloved movie musical from 1982.

Who put her up to this!?

On Thursday afternoon Kendall Jenner borrowed Scott Disick's white Bentley and went shopping at CVS near the Kardashian family compound, and after that she took her own tricked out black Range Rover to an auto body shop with a pal.

The 18-year-old reality starlet showed off her model bod in leggings boots and a Yeezus tee. Hmm, somehow we would have liked her look better if it was an 80s rock band shirt, but whatever ... she still looks gorgeous!

We're not sure what's going on with Kendall and rumored beau Harry Styles, but we have a feeling the two are going to hook up again soon! Harry is currently in Europe with his One Direction bandmates, but after their first date last month, the two had a romantic weekend together in New York City. Seeing as they spent the night at the same hotel and were inseparable for 48 hours, it seems like things are getting pretty serious!

Let's hope he didn't bruise his beautiful bod!

Justin Bieber posted a video of himself skateboarding at an indoor park yesterday, and let's just say he doesn't have a career in the sport, because he takes quite the tumble!

The singer holds his own as he launches down the half pipe, but when he attempts a trick he falls flat! The good thing is it didn't appear to hurt that badly, as JB smiled and laughed after his spill.

"Always get up when you get knocked down," he captioned the clip.

The Biebs should ask his pal Lil' Wayne for lessons!

Aww! They grow up so fast! Kourtney Kardashian gave her first born quite the birthday gift when she took her son Mason to see Disney On Ice presents Rockin' Ever After at the Staples Center in Los Angeles on Thursday Night.

The twosome looked like they were soaking in the quality time together. And even enjoyed a spin around the rink with Minnie Mouse!

The 34-year-old reality star was looking as stylish as ever, wearing black leggings, a see-through black turtle neck and fur vest. Outfitted in bright red pants, black boots, black t-shirt and midnight blue cardigan, the birthday boy was quite the dapper Dan.

Kourtney and Mason, who turns four on Saturday, were joined by a group of friends for the icy outing.

Aww!

Lindsay Lohan has had a turbulent relationship with her mother Dina in the past, but it appears the two are on good terms these days, because the troubled actress posted a mushy photo on her Instagram account that shows her mom's message "Love U xo mommy" written in lipstick.

"My mommy left this on the mirror! So sweet!" she captioned the snapshot.

Lilo's gonna need the support of her family as she deals with the drama surrounding Barron Hilton's assault in Miami, which was reportedly ordered from the Mean Girls star after she caught Paris Hilton's brother "talking s**t" about her "boyfriend."

Although Barron's father Rick Hilton told X17online exclusively there are no plans to sue Miss Lohan, we still think things are going to get a lot messier before they are cleared up!
