Curiosity may kill a cat, but it can do wonders for a friendship. Just ask these two buddies, who gave making out a try. Also experimenting are a man in Spanx and a literate Twilight star. They're the cat's meow.

1. "These Celebrity BFFs are now settled in their lives and careers. Over drinks this last weekend, one of the stars told our source that in the beginning of the friendship, the ladies weren't sure if their budding friendship was something more. So, to test the waters, the two had a little make-out session, and got the urge out of their systems. After the little romp, the two laughed it off and decided their chemistry was strictly platonic. The two have been good buddies every since. Not Jennifer Aniston." [Buzz Foto]

2. "This good-looking and award-winning male actor has always been known as being rather vain. That's why it should come as no surprise that he is asked the director to help him mask his weight gain (he is a good 25-35 pounds heavier than when he first landed the role). He is especially self-conscious about how he appears when filmed from the side. We don't think he looks that bad with the extra weight (he has always been built like a tank), but the wardrobe person has fitted him with a men's compression girdle to help smooth him out. Just don't expect to see him unbuttoning his suit any time soon." [Blind Gossip]

3. "This Twilight star has joked about their big role before to the press, downplaying the appeal of the plot and movie and books. The star revealed to our source that they have now actually read the books and now has become a huge fan! Not Rob Pattinson." [Buzz Foto]
