Neither will ever forget this moment. Carrie Underwood is currently on her Cry Pretty Tour, but she had quite the pair to root for her at a recent show in Birmingham, Alabama: her husband, Mike Fisher, and son, Isaiah.

Mike, 38, took to Instagram on Saturday, May 4, to share that the couple’s 4-year-old son was enjoying watching his mother perform while on tour. “What a night! This is Izzy’s first tour show that he’ll remember,” the retired hockey player captioned numerous photos of the concert. “He had a blast and kept yelling ‘mommy I love you’ when she came close!!”

“His mommy is a rockstar on stage and off the stage. Touring with a 3 month old is brave to say the least but if anyone can do it she sure can!! … The pictures don’t do it justice, what a show!!” Mike added, referring to their newborn son, Jacob. Take a look at the post below!

The American Idol alum, 36, responded to the post and said, “I’m the luckiest wife/mom in the whole wide world to have my boys in the audience watching me! Love you!!!” Carrie and Mike have been married since 2010 — Isaiah and Jacob are their only kids. The singer once revealed how tough it has been getting back into shape after giving birth to her youngest.

“I’m going to be honest, ‘bouncing back’ after having Jacob has been much more difficult than after I had Isaiah and I’ve been pretty hard on myself lately,” the country star said on an Instagram post shared on March 19.

“As I prepare for red carpets and for life on tour, right now I make a promise to myself to start appreciating what my body CAN do and stop focusing on what it can’t,” she continued. “I promise to stop analyzing every angle and every curve and every pound and every meal.”

“I’m going to take it day by day, smile at the girl in the mirror, and work out because I love this body and all it has done and will continue to do!” she added.

We love to see all the positivity in Carrie’s family, and now that Isaiah is enjoying seeing his mom perform, it’s only a matter of time until little Jacob is old enough to appreciate her performances too!
