Twilight stars Kristen Stewart and Robert Pattinson might be tying the knot soon.

According to In Touch Weekly, the love duo was seen shopping at Neil Lane in West Hollywood with a friend in early June and eyewitnesses were stunned when she headed straight for the engagement rings.

"She was trying on gold rings with various colored diamonds - nothing traditional," one excited onlooker told In Touch of the 22-year-old Twilight actress.

A friend of the couple told In Touch, "[Kristen] loves Rob, and she's finally ready - an engagement is a logical next step."

"In the past year, they've really heated up," the friend adds. "Moving in together, traveling together, [and] introducing each other to friends." This can mean that they might have been thinking of this for a while.

According to Marie Claire, Stewart, 22, was looking at different colored diamonds as she and Pattinson, 26, "perused the bling rings on offer."

The "Robsten" duo started dating in 2008 when they made the first Twilight movie together.

Even with all this excitement, fans still might not know about the marriage. The vampire-loving actress said that she will keep her marriage very much under wraps.

"I guarantee whenever I get married or have a baby, everyone is going to want to know my kid's name and I'm not going to say it for ages," she said. "That's just the way I want to do it. It'll come out but it won't have come from me. They're going to be really p***ed off."

According to Hollywood Life, Pattinson recently proclaimed his love for Steward in an interview in Berlin. He finally named Steward his girlfriend.

"I don't talk about my relationship," he said. "Since I started doing interviews. Cause I just don't, I've been like it since the beginning."

According to IBTimes, in an interview with Elle Brazil, the British actor opened up about his love for Stewart.

"She understands exactly how I feel," said Pattinson. "She is an ambitious woman who wants to grow as an actress. She has an excellent radar for what is good and challenges me constantly."

Hollywood Life revealed that Stewart also said she wants to have a baby with Pattinson in a report from US Weekly.

On June 23, the couple attended a wedding, where they were joined to the hip.

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

Even Breaking Dawn director Bill Condon said that they would be good parents after witnessing playing parents to their Breaking Dawn daughter, Renesmee, played by Mackenzie Foy.

"It really brought something paternal out in Rob, and Kristen was especially protective," he said.

Unfortunately, the favorite Twilight couple won't be having kids anytime soon. The US Weekly source said that they will try for a baby after the final Twilight movie, which comes out November 16, 2012.

"They know their every move is going to be scrutinized when they're promoting the film. They will decide when the moment is right."

With Breaking Dawn part 2 coming in theaters soon, fans might just have too much on their plate to digest when or if the news is confirmed.
