Christina Applegate -- who announced last week that she is pregnant -- debuted her baby bump Sunday at the Los Angeles premiere of Cats & Dogs: The Revenge Of Kitty Galore.

Speaking to Entertainment Tonight, the 38-year-old actress -- who is engaged to her baby's father, rocker Martyn Lenoble -- didn't dish on the baby's gender ("that is for me to know," she said) and would only reveal that she's "somewhere between zero and 10 months" along.

As for pregnancy cravings, she said that besides avocados, she likes "weird things at weird hours."

Her trick to dressing while pregnant? Wearing high heels!

The actress joked, "It offsets the impending growth of width."
