Kate Hudson "hates" how big her breasts have become since being pregnant.

The 31-year-old actress - who is expecting her first child with British musician Matt Bellamy - does not like how much her body is changing because it means she cannot wear the clothes she wants to, although she does admit they are fun for "certain things".

She said: "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.

"Plus, I love fashion, and having big breasts is not ideal for certain looks. They're way more fun when you're not in your clothes. Then, they're a blast!"

Kate - who also has seven-year-old son from ex-husband Chris Robinson - also reveals she is unlikely to be getting married to Muse star Matt any time soon.

She told US InStyle magazine: "I wouldn't count it out but Matthew and I kind of skipped that part and went right to the good stuff."
