Miley Cyrus was joined by her mom, 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 rumors 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 on Monday 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, which will be televised on Tuesday night on The CW, 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 was 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, TX, where he held a secret Myspace event.

Julianne Hough and Ryan Seacrest have called it quits. The couple reportedly split after more than two years together. Julianne and Ryan started dating in 2010 and, despite their busy schedules, shared plenty of sweet moments. Click through to see their many beach getaways, romantic vacations, and red-carpet snaps.

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 mom, 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.
