The happy couple is apparently thinking about some names they might choose for future kids although they're not planning to have this happen anytime soon.

"They like to play name games, like what's the most interesting and meaningful name they can come up with for their future kids. They're not in a rush," the source said. "They are still young and really into their careers, but love talking about the big family they will one day create together."

The site then pointed out how Pattinson and Twigs chose their promise rings, giving the impression that these two really are in for the long run.

"They picked the rings out together. Rob wanted to give Tahliah a promise ring over the holidays, but couldn't find the right one so he held off," an insider revealed. "They had been looking at rings together since the beginning of the year. It's like a pre-engagement ring. Very authentic and one of a kind."
