Celebrity rumors are responsible for two-thirds of all Web searches. At least that's what we heard from the uncle of a friend's cousin. Perhaps our not-so-reliable source inflated the number of rumor searches, but the shock of a fantabulous rumor is what makes the salacious tidbits so darn irresistible.

So, is the oh-so-adorable Christina Aguilera pregnant? Why did Vanessa Anne Hudgens take those infamous pictures? And does Britney actually own underwear? We have no answers on those delicious morsels, but we do know the top 20 entertainment-related rumors circulating through Search this week...

A few more whispers about rumor searches...

—Lindsay Lohan's rumored affection for ladies topped the list easily, drawing 25% more searches than the #2 item on our list.

—Wishful thinking contributed to the hopeful rumor searches on a new Star Wars flick and a Sopranos big-screen adventure.

—What are people saying about our favorite super-duper movie star Vin Diesel? We hear that's not his real name. Anything else?
