We're not sure if this is true, but the latest rumor is that Kate Hudson and boyfriend/future baby daddy Matt Bellamy have secretly gotten engaged!

After the couple (er, Kate's mom Goldie Hawn) confirmed they were expecting their first child, a source revealed to The Sun that they threw a bash celebrating their hush hush engagement! A source tells the tabloid, "It was an intimate party. They kept their engagement secret as they wanted to celebrate with their nearest and dearest before it became public knowledge."

Kate's rep has yet to get back to us, but we'll bring you the latest info as soon as we get it!
