Carrie Underwood and her husband Mike Fisher's young son is "a total champ" and he is the "best" thing that has happened to them.
The 32-year-old country music star, who married Nashville Predators hockey star Mike Fisher in 2010, gave birth to eight-month-old Isaiah Michael Fisher in February, reported Contactmusic.
"I tell (Isaiah) constantly that he's the best thing that me or Mike has ever done... (Isaiah is) just the easiest, sweetest guy. Like he's smiley. He only cries if he's hungry or sleepy... No colic. He's teething. He's been a total champ. He's just an easy sweet baby!," she said.
The couple - who met at one of the "Smoke Break" singer's concerts in 2008 - love to sing Underwood's hits to Isaiah despite her 35-year-old sports star husband changing the words to his wife's songs.
