Ryan Seacrest

When Ellen's in town, you know all eyes — including ours — are going to be trained on her every move, and so they have been since the super popular talk show host and comedian touched down in Sydney on Friday morning. Holding hands with her Australian-born wife, Portia, Ellen stopped to sing with fans, chatted to reporters and danced in front of the hundreds of peopl at the airport, before shooting straight off the Sydney's Taronga Zoo. And when we weren't on Ellen watch? We were taking a long, hard look at new pictures of Ryan Gosling (duty calls!), loving how happy and beautiful Diane Kruger was looking at the premiere of her new movie, The Host, and snooping Aussie stars at L'Oreal Melbourne Fashion Festival. This week also saw new pictures of a recently-split couple, hot guys on dad duty, pregnant stars, Kate Middleton taking the train and more. It's all in here — check it out now!

Miley Cyrus was joined by her mum, Tish, and her little sister, Noah, for a visit to the Children's Hospital of Orange County in Orange, CA, today. The radio stop was extra special, as Miley and Ryan celebrated the opening of his foundation's new multimedia broadcast center, Seacrest Studios, inside the facility. When Miley and Ryan weren't busy mingling with children and attending the ribbon-cutting for the studio, they sat down for an interview that aired on Ryan's KIIS FM show.

Miley and Ryan chatted about her recent twerking video, and she confessed that she had "been practicing [twerking] probably for the past two years." She also confirmed a new song collaboration with Snoop Lion coming up, but one topic she didn't touch on was fiancé Liam Hemsworth. The duo has been the subject of breakup rumours for weeks, though now that he's back by her side in LA, the lastest reports reveal that they are happy and moving forward with wedding plans.

Justin Timberlake hit the red carpet to celebrate the release of The 20/20 Experience at LA's El Rey Theatre last night. He was joined by newly single Ryan Seacrest, whose split from girlfriend Julianne Hough was announced last week. Ryan interviewed Justin during the event, and their chat confirmed that Justin is in fact planning on dropping a second part to the album later this year. Also on hand for the bash were Emmy Rossum, Anna Kendrick, Nikki Reed, and a crowd full of fans, who were treated to a concert by Justin that included a performance of "Mirrors." He had made his way west after stopping over the weekend in Austin, Texas, where he held a secret Myspace event.

Julianne Hough was joined by Ryan Seacrest to helped launch the new Topshop/Topman store in LA last night. She pulled double-duty yesterday, since she also dropped by the Tommy Hilfiger store opening in West Hollywood sans Ryan. Other celebrity attendees included Demi Lovato, who arrived at the event in a studded cast and crutches after she broke her foot earlier this month, and Kate Bosworth with fiancé Michael Polish.

Kim Kardashian also celebrated the new Topshop outpost with her mum, Kris Jenner, by her side. Kim recently caused a bit of a scandal when she and boyfriend Kanye West were involved in a security breach at JFK. According to reports, a TSA employee let Kim and Kanye skip airport security, so they could more easily transfer to their next flight. However, a TSA spokesman said that it was the employee, not Kim and Kanye, who was to blame for the breach.

Julianne Hough and Josh Duhamel were joined by their famous significant others at the LA premiere of Safe Haven in LA last night. Julianne wore a silver Alberta Ferretti dress to pose alongside her boyfriend, Ryan Seacrest, on the red carpet. Meanwhile, Josh went for a bright blue Ralph Lauren suit for the premiere, but opted to not walk the red carpet with his wife, Fergie. However, the couple did share a hug off of the red carpet and chatted with friends at the after party. Josh was busy yesterday, appearing on The Tonight Show as well. Other famous faces celebrating the latest Nicholas Sparks big-screen adaptation included Julianne's brother and US Dancing With the Stars dancer Derek Hough, as well as Josh and Julianne's co-star Cobie Smulders, who wore a black Saint Laurent jumpsuit. Safe Haven hits cinemas on Valentine's Day.
