"Thanks to all for the birthday wishes and to the people that share the same birthday, glad you were born too. The 30’s were good to me and I’m really looking forward to my 40’s, cause I'm late bloomer. Got everything I need for a perfect 40th…a happy and healthy lady, son, and another baby on the way….my family, closest friends and I celebrated last night with a performance by one of my favorite artists Jamey Johnson."
