U.S. actress Kate Hudson concedes she is battling the physical side effects of pregnancy as she makes her way toward her summer due date.

Hudson, 31, said in a recent interview in Britain's The Time that she has been dealing with morning sickness as well as "pregnancy brain," People magazine reported Saturday.

"I babble a lot," Hudson said. "I forget words, and how to put sentences together. I just give up."

Hudson, who also has a 7-year-old son with ex-husband Chris Robinson, also said her woozy condition led her to withdraw from the Hollywood scene for a while, which she said seemed to fuel talk that she and rocker boyfriend Matthew Bellamy were expecting.

"You're somewhere in LA, and somebody says something, and it ends up somewhere," she said.
