Robert Pattinson has decided to come back to the spotlight. The 26-year-old actor has been out of sight since learning last month that his girlfriend and “Twilight” co-star Kristen Stewart had an affair with a married movie director. A tabloid printed photos of the illicit dalliance, breaking the hearts of “Twilight” fans worldwide and prompting Stewart and the director to issue public apologies to their loved ones. Pattinson was scheduled to appear Monday night on “The Daily Show” with Jon Stewart. It’s a gentle, if obligatory, re-entry into the media machine leading up to Friday’s opening of “Cosmopolis,” the David Cronenberg drama starring the “Twilight” heartthrob. When Pattinson chatted with Stewart in 2010, the comedian invited him to return, saying, “You are making me cooler.” Fred Willard also opted for a comic comeback, appearing on Jimmy Fallon’s “Late Night” show, where he joked about his arrest for lewd conduct nine days earlier. … The former Susan G. Komen executive at the heart of the organization’s clash with Planned Parenthood has a book deal. Howard Books, an imprint of Simon & Schuster, announced Monday that Karen Handel’s “Planned Bullyhood” will come out Sept. 11. Handel is a former senior vice president of public policy at Komen. She resigned in February amid a furious public debate over the breast cancer charity’s decision to cut off, then reinstate funding for Planned Parenthood. Handel is a Republican who opposed abortion as a candidate for Georgia governor. She actively supported Komen’s move to end the grants. Last week, Komen’s founding CEO, Nancy Brinker, announced she was stepping down, and Komen President Liz Thompson also is leaving. … Sarah Palin says she won’t speak at the Republican National Convention this month in Tampa, Fla.
