CBS Films announces more of the cast for Jennifer Lopez’s new movie, ‘The Back-Up Plan.’

The studio announced Monday that “Alice” star Linda Lavin will play Lopez’s grandmother, or “Nana,” in the film, while Harold Gould of “Rhoda” fame will step in as Arthur, Nana’s love interest. Robert Klein, who has appeared on “Law & Order: SVU,” will play Lopez’s fertility specialist, Dr. Harris.

The film features Lopez as Zoe — a woman who embarks on a journey to motherhood using artificial insemination, only to meet a possible Mr. Right named Stan (Alex O’Loughlin of “Moonlight”) on the day of her insemination. The couple begins dating, with Zoe confusing their early relationship by hiding her pregnancy. After she reveals her secret, Stan unexpectedly sticks by her side. But as the birth approaches, the pressures of their new relationship and her impending motherhood could split them apart.

‘The Back-Up Plan,’ will be directed by “Six Feet Under”’s Alan Poul. The movie is set to begin filming in Los Angeles in May and will premiere in theaters in January 2010.

Jennifer Lopez, Jamie Foxx And Christina Milian may be the next stars to join the naked picture party, it’s claimed.

The latest rash of candid celebrity nudes began when intimate snaps of R&B star Cassie began doing the rounds online.

The singer responded to the photos by revealing on her blog that her computer had been hacked and snaps from her personal collection stolen.

Then on Friday, self-portraits of Rihanna posing in various states of undress emerged.

And apparently there’s more to come.

According to Missinfo, the leaked Cassie and Rihanna pictures aren’t the work of jealous exes or a canny bit of self-promotion.

Instead, they have been around for a while, and we should expect more Cassie and Rihanna candids to follow, alongside some ‘unauthorised’ snaps of Jennifer Lopez, Jamie Foxx, and Christina Milian.

Jennifer Lopez will never forget the night she and husband Marc Anthony discovered a lump on daughter Emme’s head. Emme and twin brother Max were only 3 weeks old at the time.

“We both got very nervous, very very nervous, and I just remember my heart sinking to my feet,” Lopez recalled at last night’s Noche de Niños gala benefit for Children’s Hospital Los Angeles (CHLA). “I looked at [Marc] and I said, ‘You know if anything happens, I’m not going to be OK, you know that, right?’”

Lopez and Anthony rushed Emme to Children’s Hospital, where she underwent a battery of tests, including an MRI. “Luckily, in the end,” Lopez said, “she turned out fine.”

But it turned into something more for the hospital…

Shortly after the scare, the singer-actress joined forces with CHLA to form the Maribel Foundation to help provide pediatric medical services to the less fortunate.

“I started to wonder,” Lopez said, “what if I couldn’t afford a doctor or receive the medicines, the procedures?”

Lopez also debuted a new song last night, which she wrote for her twins. A recording of the ballad was played during a video highlighting the Foundation’s work. In it Lopez sings, “Let’s keep this time for us and make it last as long as we can. It’s already going too fast.”

Jennifer Lopez attended the Noche De Ninos benefit gala in Beverly Hills, CA. on Saturday, May 9, 2009. Her mom Guadalupe and her sister Lynda were by her side along with Marc as well tonight! Jen looks amazing, doesn’t she?

Jennifer Lopez is still struggling to lose her baby weight. The singer/actor, who gave birth to twins Max and Emme last February, can’t quite shift the last few pounds. Lopez, who gained more than 27kg during pregnancy, said: “It’s funny, once I gave birth I dropped 13kg immediately and then the next 10kg came off right away. When I did a triathlon, I dropped another 5kg, and with the last 5kg I’m still struggling with.”

Despite gaining a large amount of weight, the 39-year-old beauty enjoyed being pregnant and revealed she and husband Marc Anthony would love to add to their family. She said: “I think we’ll have more children. I mean, it’s fun to do all the things we do, but nothing feels like what it is to have children and to have that joy and purpose in your life of raising another human being. “I had a great pregnancy, but I probably won’t be as lucky the second time. It was great, though. I didn’t have any of the bad symptoms, no morning sickness or anything.”

Max & Emme already have the paparazzi following them like they follow their mama! Max and Emme, who just celebrated their first birthday last February, are seen here in their yard in Miami.

Melissa McCarthy has been cast as a support-group leader in CBS Films’ romantic comedy “The Back-Up Plan,” opposite Jennifer Lopez.

The actress stars in ABC’s “Samantha Who?” and has appeared in the features “Go” and “The Nines.” McCarthy is repped by New Wave Entertainment and Talentworks.
