Too much work makes for very little wedding planning.

Amy Adams, who stars in Night at the Museum: Battle of the Smithsonian, is so busy juggling projects, she hasn’t had any time to work on her nuptials to fiancé Darren Le Gallo, she tells PEOPLE.

Asked how the planning is going at the movie’s premiere in Washington, D.C., on Thursday, Adams said: “It is not, I’m working too hard.”

Although Adams, 34, who announced her engagement to longtime boyfriend Le Gallo last year, admits she’s done “nothing” to prep for her big day, she knows what type of wedding she wants – and it’s not a big Hollywood bash. “[I want it to be] low key,” she says. “It just suits our personalities as a couple more.”

Tight Pants, Lots of Pilates

For her stroll down the Night at the Museum red carpet at the Smithsonian’s National Air and Space Museum, the starlet wore a flowing lavender dress, a far more demure look than the sexy fitted riding pants she wore for her role in the film as aviation pioneer Amelia Earhart.

“It’s going to be a little shocking to see everything in IMAX,” she admitted, adding that to get her body in top form for the big screen, she did pilates “as often as she could.”

Being surrounded by a cast of funny guys also kept her cracking up on the set. “Oh my gosh! Bill Hader, Hank Azaria and Ben Stiller – when you put those guys in a room, it is unstoppable laughter,” she says.
