The famously press-shy pair, who earlier this summer were photographed nuzzling on the set of her movie On the Road, have been spotted during several PDA-filled nights out together in Los Angeles recently.
On Oct. 4, the couple enjoyed a candlelit dinner and sipped wine at Ago in Beverly Hills, followed by a Jenny and Johnny concert at L.A's Troubadour the next night.
"Rob and Kristen were very affectionate and had their arms around each other for most of the show," says a concertgoer. "They looked very happy together."
A few nights later, Pattinson, 24, and Stewart, 20, enjoyed dinner at the popular Japanese restaurant Matsuhisa in Beverly Hills, where they shared several dishes with friends.
"They seemed very happy and comfortable with each other. Rob was attentive to Kristen and made sure she had food on her plate and a drink in her glass throughout the dinner," says an eyewitness. "They sat very close and Rob had his arm around Kristen for parts of the night as well."
After dinner, the low-key couple shared a cab with friends. "Rob and Kristen are not at all flashy. They don't have drivers, or bodyguards but just seem very down-to-earth," says a second eyewitness.
Up next for the pair: They are expected to travel to Baton Rouge, La., in the next few days to begin filming Breaking Dawn.
