Jennifer Lopez is feeling thankful on her 55th birthday!

In the early hours of Thursday, July 25, the singer marked her special day on July 24 by sharing a reflective message on Instagram alongside two photographs of herself celebrating the occasion.

Wearing a pair of pale blue silk Lady Lynne pajamas that had "JL's Golden Bday" written on them with the date, Lopez was all smiles as she was treated to a huge cake and multiple bouquets of flowers.

She posed in front of a "Happy Birthday" sign and wore a birthday headband as she put a party blower in her mouth in the snaps.

"I’ve been seeing all of your birthday wishes, beautiful videos, and posts all last night and this morning from all over the world. I have laughed, smiled, shed some tears, and when I saw the billboard in Times Square, I was completely overwhelmed," the "On the Floor" singer captioned the post, referencing a "Happy Birthday Jennifer Lopez" sign in the New York City location, as seen in one of her Instagram Stories posts.

"I really do have the best, most amazing fans in the world. I could never express how moved I am or how incredibly blessed I feel to have all of you be a part of my life. Thank you sooooo very much. 🤍🙏🏼," Lopez added.

The Atlas star shared, "It’s hard to believe we have spent all this time together. It’s funny as I sit here contemplating on the most extraordinary journey I still feel like the same girl starting out so full of energy and bravado, so ready to take on the whole world on the outside and yet so tender, fragile and sometimes frightened but always full of love on the inside. I have so much love for you." 

"I want you to know on my birthday that YOU are my biggest gift. Besides my family and friends, you have always been there for me in the good times and in the tough times. I can always count on you. And I want you to know that you can always count on me. Thank you for your caring, your understanding, your loyalty and most importantly your love. 🤍," she concluded.

Lopez then thanked fans three times and signed the post, "Always, Jennifer."
