Timberlake has been romantically linked to Scarlett Johansson after the two were seen spending time together at an after-party for his film Alpha Dog. The Lost In Translation actress also stars in Timberlake's latest music video "What Goes Around."

Tom Cruise and Katie Holmes are rarely seen in public with their nine-month-old daughter Suri because they fear she may be the target of kidnapping plots, according to media reports in the US. The last time Suri was spotted in public was a brief appearance in her father's arms during her parents' honeymoon last year, where the couple were surrounded by eight bodyguards. During the baby's appearance at the couple's wedding in Italy, the family took extra security precautions and were protected by 200 police officers, as well as members of an Italian security force. According to US publication Star, the couple fear the extreme public interest in the baby could make her a prime target for abduction. A source says, "The world was so obsessed with getting its first peek at Suri, I think Tom and Katie might have decided to keep her under wraps to prevent some wacko from trying to abduct her." Other celebrities whose children have reportedly been targets of foiled kidnapping plots include US talk show host David Letterman, Victoria and David Beckham and Russell Crowe

The widow of charismatic TV naturalist Steve Irwin broke down in tears on American TV on Wednesday night when she described how her children were coping without their beloved father. Terri Irwin appeared on the Tonight Show with Jay Leno and wept as she recalled the difficult days following the Crocodile Hunter star's death last September from a stingray barb to the chest. She also discussed how kids Bindi and Bob were dealing with the tragedy. Yesterday Terri appeared on the Ellen DeGeneres Show where she confessed she often felt her marriage with the late conservationist was a figment of her imagination. She said, "It ebbs and it flows and I tell you, sometimes I expect him to walk in the door, and other times I just think it's like one of those really good movies that you want to remember. Sometimes you think, 'I'm not remembering all the last 14 years,' but I think that's just a protection device." Terri added her husband had never been worried about death, recalling, "Steve was never afraid for his own mortality. Countless times he has said to me, 'Okay, now I can die. This is the most incredible thing I've ever done, now I can die,' and then we'd go and swim with the manatees, and then he'd go, 'Okay, now I can die.'"

But despite taking time off from official engagements to recover from his ordeal, Schwarzenegger is struggling to regain a clean bill of health. He says, "I don't think I can remember ever having had pain - ongoing pain, 24 hours a day - like after this operation. So this is really annoying to me. The only time when I don't have pain is when I work."
