Twilight heartthrob couple Robert Pattinson and Kristen Stewart are reportedly planning to tie the knot.

According to a report from Life & Style, Pattinson who had ended his four-year relationship with Stewart after it was confirmed that she cheated on him with her Snow White and the Huntsman director Rupert Sanders, discussed dating again and even brought up the topic of marriage during a romantic getaway to Palm Springs.

"They went away together to discuss their future and decided that they can't live without each other," a friend close to couple told to the magazine, "Marriage was definitely a topic of conversation."

"They are inseparable and 100 percent back on," the source continued, "I wouldn't be surprised if they just suddenly eloped! Kristen is adamant that they should fully commit and move forward. Of course, she was the one who suggested running off to get married."

"Rob's addicted to her, even though he knows she's bad for him," the insider added, "Their relationship was so toxic. All his friends are just praying he doesn't give her what she wants."

It was previously reported that Pattinson's family and friends are not happy with his reunion with Stewart.

"It's still so unstable. They have a lot of baggage," a source told Hollywood Life, "Rob's obsessed with her but he knows she's not necessarily good for him and he knows a lot of his friends and his family are dead set against him taking her back.

"So he doesn't talk about it much because he's embarrassed. And we have a right to be worried because we see how much she f***s him up."
