Country music star Carrie Underwood says her son Isaiah is the "best thing" in her life.
The 32-year-old - who married hockey star Mike Fisher in 2010 - gave birth to Isaiah Michael Fisher in February and the parents are besotted with the little "champ", reports femalefirst.co.uk.
Underwood said: "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!"
