It sounds like Robert Pattinson will be one happy birthday boy, if Kristen Stewart has anything to do with it.

Kristen is reportedly has big plans for her honey to help him celebrate turning 27 on May 13, according to Hollywood Life.

“Kristen is super excited to totally spoil Rob on his birthday this Monday," a friend of Kristen's reveals. 

For starters, she is letting him know what the future holds.

"She is getting his charts done — his astrological charts from a really cool numerologist,” the source says.

Also, Rob better get his swimsuit ready.

“Kristen has a special day and night planned for Rob, which will include swimming, friends, music, and of course their dogs Bear and Bernie," the insider adds.

"She’s not revealing too many details because she wants it to be a surprise for him,” the source continues. “She just wants to totally shower him with love and affection.”  

We love what Kristen has planned! Sure, it might still be a little chilly for swimming, but we have a feeling that they won't have any problem coming up with ways to stay warm (hint, hint).

We hope Rob has a great day welcoming his new moon year  and we also hope we'll get to see pics of him in a tiny bathing suit.
