UFC octagon girl Arianny Celeste is ready to enter motherhood.

Celeste, 34, announced Tuesday that she is pregnant and expecting her first child with her boyfriend, Taylor King. She shared the news on Instagram with a photo revealing her baby bump, along with a short letter written to her future son or daughter.

Baby,

I’ve been waiting for this moment my entire life! I promise to teach you about the beauty of the world and to love with no restrictions or division. In turn, you have already taught me so much about kindness, empathy, and faith. Through all of the chaos, you have helped me to stay strong and grounded. You are already loved so soooo much!! I can’t wait to meet you my baby!

Love,
Mommy

Celeste told Us Weekly that she is due September 28. She said it was her mother who first had a sense about her being pregnant.

“My mom, for some reason, asked me to take a pregnancy test,” Celeste said. “(Moms) always seem to know. I went to the store and got two tests, and sure enough I was pregnant. I couldn’t wait, so I called my boyfriend immediately even though he was working at the time.”

Celeste made her debut as a UFC octagon girl in 2006 and has been among the most popular ring girls ever, having won “Ring Girl of the Year” a record five times at the World MMA Awards.
