Beyoncé Knowles-Carter finally got around to thanking her #BeyHive for their avalanche of birthday wishes on social media.

The mom-of-three thanked her loyal fans in a heartfelt message posted to her official website, Beyonce.com.

The middle-aged singer hit her 40th milestone on September 4, but waited until Thursday, Sept. 23, to address her most loyal devotees who sent their best wishes.

"As Virgo Season comes to an end, I hope my fellow Virgos had great birthdays," she wrote.

"I'm so thankful for every inspiring human who took the time to send me all the beautiful messages. I cried tears of joy and was covered in chilly bumps. Your VIDEOS, YOUR POSTS, YOUR countdowns, your playlists and your well wishes, I will cherish forever. I'm grateful to everyone involved, especially, the fans, for the time and level of detail it took to organize such beautiful tributes."

The "Halo" singer added:

"I admire and respect all of you and I thank you from the bottom of my heart. This is the first year that I really understand what it means to be alive and to live in the moment. It's the first time that I have an understanding of how fragile life truly is, how hard life can be at times, and therefore how important it is to stop and smell the roses during the good times.

"I thought I knew that at 21 or 30... but I didn't.

"The more mature I become, the more I understand and the deeper my joy grows. There's a freedom and liberation knowing that I've made it to the other side of my sacrifice. I'm finally giving myself permission to enjoy the seeds I've worked so hard to plant my whole life."

The "Lion King" star, pictured with daughter, Blue Ivy, then turned her attention to people who believe life is over at 40, stating, "This has absolutely been the best I've felt in my life. I'm so grateful to be GROWN, GROWN!"

She also addressed rumors that she is older than her stated age:

"Most of y'all met me when I was 15, and we have grown up together. You bring soooo much joy into my life. I hope my art can continue to bring a little joy into yours. I Love You Deep Deep Deep Deep Deep."
