Robert Pattinson and Kristen Stewart have been getting really close these past few weeks — and Pattinson’s feelings for his Twilight costar are growing stronger by the day. According to insiders, Pattinson — whose texts to Stewart were blamed for ending her relationship with actor Michael Angarano — may be a man on a mission.
“Rob’s dedication to winning Kristen’s heart says something,” a source told a tabloid. “He’s falling for her fast and seems to be head over heels.”

But it seems Kristen, 19, might be keen to take things slower.

It was recently reported that Stewart refused Pattinson’s offer of a free vacation.

“Kristen told Robert she’s incredibly fond of him, but doesn’t want to race into a serious relationship,” a source told the National Enquirer. “And she made it clear his constant pursuit is putting too much pressure on her.”

The source added that Twilight producers were so worried that Pattinson might blow up his on-camera chemistry with Kristen, “they begged him to chill and give Kristen space.”

Twilight insiders recently confirmed Rob and Kristen had “hooked up” — but insisted they weren’t boyfriend and girlfriend.

“They’ve decided to be more public about going out now,” said the source. “They’re not boyfriend and girlfriend, but they’ve definitely hooked up.”
