Hollywood actress Kristen Stewart feared that her boyfriend Robert Pattinson will leave her because of the undying issue of her infidelity.

One of the possible solutions that Kristen has thought of is getting a boob job.

A source said that "[Stewart] and [Robert Pattinson] is at a critical crossroad and she is frightened that unless she does something radical, [Pattinson] will kick her to the curb. Kristen is terrified that Rob is going to leave her for someone else. She has always been insecure about her boobs, and she is totally convinced Rob would find it a massive turn-on if she had even a subtle size increase."

"Whenever they're out together, she's always on high alert to see which girls seem to capture his attention, and they're always girls with big boobs. She's desperate to hang onto Rob, and thinks a breast augmentation would do the trick." the source quickly added.

Another report claimed that one of the secrets of Robert Pattinson and Kristen Stewart's relationship is having a good sex after a fight.

According to Showbiz Spy, Robert Pattinson and Kristen Stewart are rocking away, hot and steamy, as they kiss and makeup since the so-called cheating scandal.

Stewart is now playing the sex kitten role. Pattinson apparently loves her red hot pedicures and those spike heels of hers. As we have all seen, she has been sporting see-through dresses and spikes on the red carpets these days.

Although she is auctioning off one nearly nude number, a dress auction for charity. It appears that Pattinson and Stewart are into a makeup sex game that has them hooked.

"All the fighting put the heat back in their romance. She always has a blood-red pedicure. Kristen is a real tomboy, but she has been rocking skirts and stilettos a few times a week because she knows Rob loves it. And even if she has sweats on, she makes sure to wear sexy lingerie," an unnamed source told Showbiz Spy,
