Robsten PDA! Kristen Stewart and Robert Pattinson proved to their supporters that they're still going strong by stepping out on Wednesday, April 3 holding hands.

Pattinson, 26, and Stewart, who turns 23 next Tuesday, April 9, enjoyed a day out with friends in L.A.'s Los Feliz neighborhood, as first revealed via X17. The Twilight costars and real-life couple of over three years, grabbed sushi with their pals and went for stroll together.

The couple looked "really happy and lovey-dovey," an eyewitness told PopSugar. "Kristen grabbed his arm, and they were walking and joking."

They both wore dark sunglasses and casual T-shirts for their day date. Stewart also styled her trademark backwards cap and sneakers.

The superstar twosome has been making up for lost time after Pattinson's mid-March return from Australia, where he had been shooting The Rover for over two months.

Since his return, Pattinson and Stewart have been spotted out together several times in public. On March 19, they visited a karaoke bar with friends and on March 23 -- after Stewart's solo appearance at the Nickelodeon Kids' Choice Awards -- they partied at Hollywood's Chateau Marmont with pal Katy Perry.
