On Tuesday, People reported that the Twilight star may be ready to tie the knot with his lover FKA Twigs. According to the site, these two are wearing promise rings to show their commitment to each other.

"He wants to marry her," a source told the site, mentioning that Pattinson is "much more calm and happy than before."

It also appears that the two may have already taken a big step in their relationship by moving in together.

"They are inseparable when they are together," the insider said. "They live at his house."

Pattinson previously dated actress Kristen Stewart, making them one of the most popular celebrity couples in the entertainment industry. Considering that the actor is "much more calm and happy than before," that might give some curiosity if this was a reference on his former relationship with Stewart.

There was a previous report from Hollywood Life that stated that Pattinson wanted to see Twigs at the 2015 Brit Awards, but couldn't arrive until afterward.

"He couldn't make it to the actual show, but did manage to get to the after party," a source spilled. "He is her biggest fan and just dotes on her."

These two may not get too much time to spend together as they work hard in their careers, but this apparently makes their time together that much sweeter.

"Yes, they are crazy about each other and the time apart definitely worked in their favor," the source said.
