AceShowbiz - The Hollywood actress is expecting a child with her rocker boyfriend Matt Bellamy, and she admits the rush of hormones clouds her thinking and makes her feel high.

She tells Extra, "Being pregnant is wonderful. You do get the pregnant mush-brain... you know what it's like? It's like getting stoned."

Kate Hudson has also revealed her doctor has advised her to keep her food cravings in check after she gained nearly 70 pounds (32 kilograms) during her last pregnancy.

She adds, "My doctor looked at me and goes, 'So let's try not to gain 68 pounds this pregnancy,' (I told her I wasn't) promising anything."

The Almost Famous star has a son, Ryder, with ex-husband Chris Robinson.
