And, luckily, the actress, singer, and New York Times bestselling author, 24, hasn't suffered morning sickness or any other common pregnancy woes. "It's good," she said Monday on Chelsea Lately. "Everything's been really easy. Didn't get sick."

One weird development: Her supersized pregnancy boobs! "These are new," the star said, gesturing to her chest. "These are, like, new and different, so that can be a good and bad thing, but other than that, seriously, it's pretty easy!"

During her freewheeling chat on Chelsea Handler's show, Duff also dished on her chaotic Aug. 11, 2010 wedding to NHL star Comrie, 29, in Santa Barbara.

"Disaster is a small word compared to how crazy it was!" Duff recounted.

As she's previously shared, Duff's tooth fell out the morning of her special day while she was chomping down on a bagel; her wedding planner Mindy Weiss tracked down a dentist for an emergency procedure before the ceremony.

The calamity continued just before the outside ceremony -- when helicopters and photographed besieged the couple and their guests.

Finally, Duff and Comrie's pastor took matters into his own hands. "My pastor steps out from underneath the flowered arbor thing," Duff revealed, "And holds up a fake Uzi or a big machine gun -- and starts blasting at the paparazzi in front of all of our guests," she said, mimicking machine-gun fire sounds.

At last, the befuddled groom pulled back the minister. "My husband was like 'Buddy, what are you doing?!'"
