JULIA ROBERTS: Hollywood actress Julia Roberts is helping raise awareness about the dangers posed by toxic smoke from unsafe and inefficient stoves.
The "Pretty Woman" and "Eat Pray Love" star has joined the Alliance for Clean Cookstoves as a global ambassador. Roberts is to speak about the issue of cookstove safety in an interview with U.S. Secretary of State Hillary Clinton for the actress' "Extraordinary Moms" special, airing Saturday on the Oprah Winfrey Network.
"Nearly 2 million people around the world -- mostly women and children -- die each year from an activity that many of us take for granted: cooking for our families," Roberts said in a statement. "I am proud to stand with Secretary Clinton to work to reduce the senseless and preventable deaths from unsafe cooking conditions in the developing world and I look forward to contributing to the important work of the Global Alliance for Clean Cookstoves."
Roberts, along with Clinton, the United Nations Foundation and other alliance partners, aims to get 100 million homes to adopt clean and efficient cookstoves and fuels by 2020.
Clinton announced last year the formation of the alliance, a public-private partnership led by the U.N. Foundation, to "save lives, improve livelihoods, empower women, and combat climate change by creating a thriving global market for clean and efficient household cooking solutions," the group said in a news release Friday.
MICHAEL ROSENBAUM: Actor Michael Rosenbaum says he had a great time reprising his role of Lex Luthor in the series finale of the U.S. supernatural drama, "Smallville."
Rosenbaum, 38, left the show three years ago.
He recently taped his part in the 2-hour series finale, which is to air May 13 on The CW.
Asked what took so long for him to come back to the show, the actor told TV Guide Magazine: "It just never quite clicked, and I felt like I had accomplished what I needed to. I'm so flattered that the fans wanted me back, but I was busy. I was doing other things, working on me, growing my hair. ... I was about to do [the comedy series 'Breaking In'] and realized that if I don't do this now, it's never gonna happen. And the fans will never forgive me. I owed them. And you know, I wanted to do it."
Rosenbaum said he was grateful for the opportunity to return to "Smallville" and help wrap up the 10-year-old series.
"It was probably one of the best days of filming I have ever had. I didn't want it to end," he told the magazine.
"People, former crew members -- who weren't even working on the show anymore -- came to see me. It was like a big family, their arms were open wide and welcoming. And I was so nervous. I've said this before, but I was like: 'Oh my God, can I do this? It's been three years. I have hair now... is the bald cap gonna work?' Everything came together, the bald cap worked, the scenes I did were really fun and good and layered," he said.

"Our beautiful son Tate has arrived safe and sound! We are all so happy and excited," Bunton said via Twitter Friday. "Thanks and love to you all."

FRANK LANGELLA: Tony Award-winning actor Frank Langella is to star in a staging of Terence Rattigan's drama "Man and Boy," New York's Roundabout Theatre Company said.
Directed by Maria Aitken, the play is to begin previews Sept. 9. It is scheduled to officially open Oct. 9 at Broadway's American Airlines Theatre.
This will be a limited engagement through Nov. 27.
Langella has won Tonys for his performances in "Seascape," "Fortune's Fool" and for "Frost/Nixon." He was nominated for an Academy Award for his portrayal of Richard Nixon in the film version of "Frost/Nixon."
The actor returns to Broadway and Roundabout Theatre Company following his 2008 performance as Sir Thomas More in "A Man for All Seasons."
Aitken recently directed a popular stage play based on Alfred Hitchcock's "The 39 Steps."
Additional cast members and the creative team will be announced shortly, Roundabout said Friday.
"At the height of the Great Depression, ruthless financier Gregor Antonescu's business is dangerously close to crumbling," said a synopsis of "Man and Boy."
"In order to escape the wolves at his door, Gregor tracks down his estranged son Basil in the hopes of using his Greenwich Village apartment as a base to make a company-saving deal. Can this reunion help them reconcile? Or will this corrupt father use his only son as a pawn in one last power play? 'Man and Boy' is a gripping story about family, success and what we're willing to sacrifice for both."
