Robert Pattinson and Kristen Stewart are making one of the hottest couples in Hollywood, but Pattinson recently confirmed in an interview that he is not marrying Kristen Stewart – at least not yet.

It is true that Pattinson and Stewart are very much in love with each other, cuddling up behind the scenes at the Teen Choice Awards Sunday night. The duo snatched away the Choice Movie: Romance for The Twilight Saga: Breaking Dawn Part 1, and the Ultimate Choice Award for Twilight. Stewart also won Choice Movie Actress: Romance for her role in Snow White & The Huntsman.

The Breaking Dawn actors were also seen laughing and joking with costar Taylor Lautner backstage.

However, marriage rumors have been quickly cleared when Robert took it to a recent interview with Black Book magazine.

"There was a magazine, with these pictures, saying I was getting married. No one ever knows what is true or what isn't," the 26-year-old actor said in the September issue of the magazine.

"Even my own mum called to ask me if it was true," Pattinson added.

Both of the “Twilight” co-stars are focusing on their careers, and they have been keeping their romance as private as possible.

However, recent rumors point to an upcoming tell-all biography by Kristen Stewart and Robert Pattinson, in which they would reveal darkest secrets of their sex life.

The rumored tell-all book on the sexiest Hollywood couple is “going to be a very juicy read,” according to OK! Magazine source.

In a press panel at the Comic-Con two weeks ago, the couple talked about the sex scenes in The Twilight Saga: Breaking Dawn - Part 2.

"We're supposed to have mind-boggling, other-worldly ... sex," Stewart whispered at the press panel. Co-star Mackenzie Foy, 11, was sitting just two seats down.

"Nothing about this series is raunchy," she said, as Pattinson looked at her surprisingly.

"We tried and they told us it was rated R," Stewart said of the sex scene the Twilight couple attempted to make.

While marriage may not become reality just yet, Pattinson and Stewart have at least talked about having a baby together.

"They would talk about how they would raise their own children," a source told Us Weekly.

"Kristen would say, 'Well, I'd never do this or that.' Sometimes it would start off as a joke, but you knew they were really thinking about it."

"Kristen was talking to a pregnant guest and told her that she would love to have a baby with Rob," said the source.
"She thought it was so cool -- at one point she touched the woman's belly to feel the baby kick."

"He is over-the-moon in love with Kristen," according to a Twilight source.

"For him, she's The One, so it's just a matter of when they decide to have kids."
