Will Kristen Stewart soon become the glummest glowing bride ever? In a sure sign that promotion for "Twilight: Breaking Dawn Part 2" is kicking into high gear, engagement rumors are floating around the smile-stingy actress, 22, and her on- and off-screen leading man, Robert Pattinson, 26.
According to In Touch, K.Stew was recently spotted browsing the glittery wares at Los Angeles jeweler-to-the-stars Neil Lane.
"She was trying on gold rings with various colored diamonds -- nothing traditional," a spy told the tab.
On Wednesday, Beverly Hills-based Claude Morady Estate Jewelry raised eyebrows when it posted a link to the story on Facebook with the message, "We can neither confirm nor deny firsthand knowledge of this rumor.... :)."
The question-popping speculation comes hot on the heels of an Us Weekly report that claims Robsten, who were first linked in 2009, are eager to take a cue from Edward and Bella by procreating.
"He is over-the-moon in love with Kristen," gushes a source. "For him, she's The One, so it's just a matter of when they decide to have kids."
Stewart is supposedly on board with the domestic bliss plan, starting with the betrothal.
"She loves Rob, and she's finally ready," oversells a source to In Touch. "An engagement is a logical next step. In the past year, they've really heated up: moving in together, traveling together, introducing each other to friends."
In light of their together-time and recent touchy-feeliness at the Cannes Film Festival, a bigger commitment wouldn't be outside the realm of possibility for the low-key pair.
