Carrie and Peterborough, Ont.-native Mike tied the knot in 2010 after two years of dating. Shortly after they said "I Do," Mike was traded from Ottawa to Nashville where he and Carrie have made their home. Now that his NHL season is over, the hockey pro is enjoying some down time at home with the family and Carrie looks to be itching to get back to work. Her new Instagram post confirms that the seven time Grammy winner is back in the studio working on new music. And with Isaiah as inspiration, one thing's for sure – Carrie's future hits will be overflowing with love.
