Maybe it's because of his humble, "Tiger Beat" beginnings on "21 Jump Street," but Johnny Depp is happy to show just how grateful he is for his success. On Monday night in Wisconsin, the A-lister got up close and personal with hundreds of fans as he was filming the Michael Mann-directed John Dillinger drama, "Public Enemies." According to WBAY-TV, Depp shook hands and made small talk with the crush of admirers, and even shared a coochie-coo moment with a stroller-bound tot. "I told him, you don't know how much this means to us, you being here," swooned one female fan, "and he turned around and said, 'You don't know how much you guys mean to me.'" Another Depp enthusiast said he was "very gentle" and gushed that his hands were "very warm." The actor-cum-good egg has gone out of his way to be gracious to the crowds that have turned out for filming, recently doing similar meet-and-greets in Illinois and Indiana.

Don't expect to find a poster of Lindsay Lohan tacked onto the wall at Hogwarts. Rupert Grint, who plays Harry Potter's redheaded sidekick Ron Weasley, reveals the less than impressive encounter he once had with the thrice-rehabbed starlet. "I met Lindsay last summer and she talked about herself a lot," the actor tells the London Sun. "She said she was going to win an Oscar before she turns 25. I just kept thinking, 'But you can't act.'" Proving that he's wise beyond his 19 years, Grint adds that he has no desire to run into any of Lohan's frenemies. "I haven't met Paris and don't want to either," he declares. "She and Lindsay are the type of girls you need to stay away from."

Cynthia Nixon attends "A Night to Benefit Raising Malawi and UNICEF" on Feb. 6, 2008.

Cynthia Nixon is going public with the story of her own health crisis in a bid to encourage women to get mammograms. The actress, who is currently out stumping for the forthcoming "Sex and the City" movie, reveals to "Good Morning America" that she was diagnosed with breast cancer a year and a half ago. Seems she had gone for a "completely routine mammogram" when she received a call from her gynecologist. "She says, 'Well, I have some -- it's not such great news," recalls Nixon, who admits she was "scared" but dealt with it by reminding herself, "If it's going to happen, this is the best way for it to happen -- that it's found so early, and we can just get right on it." Still, she says that Christine Marinoni, her girlfriend of four years, was "very scared" and "in a panic" about the diagnosis. After discussing her illness with her two kids, Nixon, whose mother also battled breast cancer, quietly underwent a lumpectomy and several weeks of radiation. "I didn't want the paparazzi at the hospital, that kind of thing," she says of her silence. The actress is now an ambassador for the Susan G. Komen for the Cure Foundation, and she's hoping women will stop living in fear. "The only thing to really be afraid of is if you don't go get your mammograms," she says, "because there's some part of you that doesn't want to know, and that's the thing that's going to trip you up."

If you have some Kleenex on hand, don't miss Martha Stewart's loving tribute to her pooch, Paw-Paw, who passed away last Saturday. In a waterworks-triggering post on her Web site, the domestic doyenne remembers her nearly 13-year-old fluffy friend as a "spectacular chow and an even more spectacular dog. He was always my loyal companion, displaying the most agreeable temperament." Martha says in his last days, Paw-Paw "just stopped eating and drifted off to deep sleeps, where he now rests peacefully, and, I'm most confident, quite happily. I will miss him, always." The pooch's passing comes a month after Oprah Winfrey lost her beloved cocker spaniel, Sophie, to whom she recently dedicated a show investigating puppy mills.
