Kate Hudson is expecting a little girl! And she didn’t need an ultrasound to tell her. No, she preferred to make her prediction the old fashion way – using good old maternal instinct and a touch of mysticism.

The very pregnant actress demonstrated the latter during an interview with ET correspondent Samantha Harris. The two were discussing Hudson’s upcoming film, “Something Borrowed,” when talk turned to babies.

Hudson is pregnant with her second child, her first with her British rocker boyfriend, Matthew Bellamy.

One of Harris’ first questions was if the expectant mother knew the sex of her new baby. The expectant mother replied in the negative, but offered to try deducing that tidbit of information through a traditional technique called pregnancy dowsing. This age-old practice involves suspending a pendant over the belly. The pendulum like movement of the suspended object is interpreted to reveal whether or not the unborn baby is a boy or a girl.

Hudson told Harris the method proved accurate during her first pregnancy, when she gave birth to a baby boy. Ryder, her son with ex-flame Chris Robinson, is now 7.

This time the reading indicated the gender to be female.

Hudson also told Extra’s Renee Bargh she believes her second child will be a girl.

“It seems like my family female lineage… she’s just wild in there, just dancing all over,” she said.

If her prediction is right, older brother Ryder may be disappointed. He’s apparently hoping for a little brother, not a sister.

On her new curves:
“I hate it. I’m usually an A cup and I’m getting close to a D cup. Big breasts are fun for certain things and really not fun for other things.

On being pregnant:
“Being pregnant is wonderful. You do get the pregnant mush-brain… you know what it’s like? It’s like getting stoned.”

“Something Borrowed,” in which Hudson co-stars with Ginnifer Goodwin and John Krasinski, opens in theaters May 6.
