Heidi Montag replaces size-F breast implants with C-cups. Plus Jennifer Aniston says her hair stylist "chopped all of my hair off": See Us Weekly's top stories from Wednesday, Nov. 6, in the daily roundup. 

Bigger isn't always better -- just ask Heidi Montag. Three years after famously going under the knife to get size-F breast implants (along with nine other plastic surgeries in a single day), the former Hills star returned to the OR to downsize her bust. Now, in the new issue of Us Weekly, she's opening up about the procedure and proudly showing off her brand-new C-cup implants.

Jennifer Aniston is making hair-story once more. The actress, 44, had more than six inches lopped off of her famous head of dirty-blonde hair last Thursday. "Chris McMillan actually chopped all my hair off!" Aniston clarified to Vogue.com that there was no master plan behind the latest cut. "I actually don't have any red carpets coming up. This is truly just for me!"

No one ever said she was down-to-earth! In early 2015, Lady Gaga will become the first artist to sing in outer space, Us Weekly can exclusively reveal.

Is there something in the water in Hollywood? Short hair is all the rage these days -- celebs including Jennifer Aniston, Pamela Anderson, Kristin Chenoweth, and Jennifer Hudson have debuted dramatic new bobs and pixie cuts in recent weeks, and others are following suit. The latest star to join their ranks? Jennifer Lawrence.

No broken marriage here! Newly surfaced photos of Will Smith getting mighty close (and partially nude) with his young Focus costar Margot Robbie have sparked rumors that the actor has been cheating on his wife of 16 years Jada Pinkett Smith. However, sources reveal to Us Weekly that everything is still intact in the Smith household.
