Reese Witherspoon stopped by the March 24 Today show to talk about her role in Monsters vs. Aliens – check out the video clip.

Is the Reese Witherspoon pregnancy rumor true? We’re betting not… but we’ll be on bump watch until further notice.

Is the next step a wedding? No Reese Witherspoon/Jake Gyllenhaal wedding news to report just yet, but it sounds like moving in together is a step in the right direction.

The as-yet-titled Cameron Crowe film is written by Crowe, who is also producing along with Scott Rudin.

Cameron Crowe is the man who brought us “Say Anything,” “Jerry Maguire” and “Almost Famous.” This marks the first time that Ben Stiller and Reese Witherspoon have starred together.

Reese Witherspoon, Hugh Laurie, Will Arnett, Stephen Colbert, Seth Rogen, Rainn Wilson, Kiefer Sutherland and Paul Rudd will all be part of “Monsters vs. Aliens,” produced in Ultimate 3-D technology.

Variety magazine said this of the “Monsters vs. Aliens” plot:

“Story, which reinvents the classic ’50s monster movie as a modern-day action comedy, centers on California girl Susan Murphy (Witherspoon), who is unexpectedly clobbered by a meteor full of outer space gunk and mysteriously grows to 50 feet tall. She is captured and held in a secret government compound. The world learns that the military has been quietly rounding up other monsters over the years, including the brilliant but insect-headed Dr. Cockroach, Ph.D. (Laurie) and the macho half-ape, half-fish the Missing Link (Arnett).”

The rest of the cast goes like this:

• Seth Rogen plays B.O.B., an indestructible goo (think the Blob)
• Stephen Colbert plays the president of the United States
• Rainn Wilson, as evil alien Gallaxhar
• Kiefer Sutherland plays General W.R. Monger
• Paul Rudd as Susan’s fiancé, Derek

Sadly, we’ve got a bit of a wait for this — “Monsters vs. Aliens” is expected to be released in March 2009.

Give me a break dept: Apparently the relationship between Reese Witherspoon and Jake Gyllenhaal is drawing negative response from Ryan Phillipe (her ex), Kirsten Dunst (his ex), and Naomi Foner (his mother). If this story is true, then Kirsten had hoped to reunite with Gyllenhaal. And supposedly his mother had hoped he would find a younger woman. Meoooowwww. Witherspoon turns 32 in March. What an old bag. Gyllenhaal will be 28 in December. Dunst will be 26 in April.

Witherspoon with appear in Tokyo Suckerpunch and Four Christmases this year. Gyllenhaal will appear in Brothers this year. Rumor is that they’re getting closer to an engagement.

The movie Four Christmases (Dec 2008) is a comedy starring Reese Witherspoon and Vince Vaughn. It seems that Witherspoon is balking at the way the sex scene is written. But as Page Six points out, with Vaughn being one of the producers on this project, the scene is unlikely to change. Body double time?

The other problem with a scene rewrite is that the Writer’s Guild is still on strike. In fact members picketed the Four Christmases set a few weeks ago, chanting “quiet on the set” and “no rewrites”. (Video clip below.)

Also appearing in Four Christmases are Kristin Chenoweth, Sissy Spacek, Mary Steenburgen, Robert Duvall, Jon Favreau, Tim McGraw, Dwight Yoakam, Stephanie Venditto.

Vaughn will also appear in Outsourced and The H-Man Cometh in 2008. Witherspoon will also be in Tokyo Suckerpunch.

[By the way, if you don't know who Kristin Chenoweth is, she's the radiant "Olive Snook" on the brilliant new American TV series Pushing Daisies (British slang for being dead and buried).]
