Where did Rihanna spend the night? What does Gene Simmons think about her? Who is going to be a mom? And the latest X-Factor rumors in this edition of the juice.

Rihanna spent the night at Ashton Kutcher’s house! She arrived around midnight and left around 4 am. Photogs were able to snap some blurry pictures of the beauty from Barbados as she left Ashton’s pad . . . hopefully Demi hasn’t heard about this yet.

Speaking of Rihanna, Gene Simmons had something to say about her. He says that he is tired of “karaoke girls” and then said that is all performers like Rihanna are. Ouch.

Reese Witherspoon’s birthday is today, so a big happy birthday goes out to America’s Sweetheart! Witherspoon has some other big news as well. . . SHE IS PREGNANT! This will be her third child, (her first two children she had with ex-hubby Ryan Phillippe), but her first with her current boyfriend.

Once again, there is a brand new rumor about the X-Factor. We’ve known for awhile that there has been talk about who will be a new judge, and earlier rumors threw around names like Britney Spears and Janet Jackson. But now sources are saying Fergie of Black Eyed Peas fame will be on the show. We’ll believe it when we see it.
