The actress showed off her growing baby bump while wearing a Canadian Tuxedo for a photo shoot in Malibu Wednesday. Kate rocked the ripped jeans look with a hat and red heels ... and was all smiles in a hot blonde wig.

She and her BF, Danny Fujikawa, announced last month they're having their first child together ... a girl.

Kate said it was the sickest she'd ever been during a first trimester ... so it's good to see she's feeling better -- and looking fantastic -- now.
