Way to go Kristen! Following their 64 day separation, Kristen is ‘doing everything she can to make thing work’ with Rob, and she has totally changed her attitude. How great!

Kristen Stewart is making big changes for her man! Robert Pattinson and Kristen became reunited in March when he returned from Australia, and they have been happier than ever since then. A new report now says that Kristen has become “lighthearted and fun” since they got back together, and she is “much more committed to Rob.” How great!

Kristen Stewart Changes Her Attitude For Robert Pattinson

Kristen, 22, attended the Kids Choice Awards on March 23, and she was seen laughing and hanging out with her BFF Katy Perry.

“Kristen was lighthearted and up for fun,” a source tells In Touch. “Something has definitely changed.”

She has got her man back, that’s what!

“Kristen’s being a real sweetie,” said the source. ” She’s much more available, much more committed to Rob. Kristen’s doing everything she can to make it work. She’s been a lot cooler.”

She sure has! HollywoodLife.com previously reported that Rob was so impressed with how independent and cool Kristen was while he was away working, and it looks like her brand new attitude is doing wonders for their relationship!

“Before the thing with Rupert [Sanders], Kristen played hard to get. Not anymore. She is going out of her way to prove herself.”

Good for you, Kristen! This fresh, new carefree attitude is just what Rob wants. Keep it up girl!

What do YOU think HollywoodLifers? Do YOU think it’s great that Kristen is making so much effort?
