KANYE WEST surprised KIM KARDASHIAN for Valentine's Day with 1,000 red roses.  She even posted a picture of herself surrounded by some of them.

 

 

But Kanye was seriously upstaged by JASON DERULO . . . who gave his girlfriend JORDIN SPARKS TEN TIMES AS MANY.

Jason sent 10,000 roses to Jordin's hotel suite in Hollywood on Friday.  He Tweeted a picture of the insanity along with the caption, "I only wish I could have fit 10,000 more in here."

 

 

 

Jordin took some of the flowers home, but donated the rest to hotel staff and guests.
