It's official:  CARRIE UNDERWOOD is now full-on in love with Ottawa Senators hockey stud MIKE FISHER.  I know this because she wrote it in the liner notes of her new album "Play On", (--which drops today).  Check it out . . .

. . . "Thank you #12.  You are the most amazing addition to my life!  You are such a wonderful person and have had such an amazing hand in the building of this album and in the growth of me as a person. 

. . . "I love you so much!  You make my life better in every way!  I thank God for you every day . . .  xoxo, Carrie."  (--#12 refers to Mike's jersey number.)

Heres a look at Mike: (cute...no?)
