Corey Simms' daughter, Remington Monroe, is already a year old and days ago, she celebrated her big day with a birthday party with her 6-year-old twin sisters, Ali and Aleeah.

Before the Teen Mom 2 kid's party, her father, who was previously married to Leah Messer and is currently married to Remi's mom, Miranda, shared a special tweet with his fans and followers in honor of his baby girl.

Corey and Miranda Simms tied the knot in June 2013 and in November of last year, several weeks before Miranda's due date, they welcomed their first child together. One year later, Corey's father, Jeff, who is often seen on Teen Mom 2, shared a couple of photos of their daughter's birthday party in West Virginia.

"Remington turned a year old today! She is such a sweet little baby girl and a blessing to our family. Love her!" Jeff wrote in the caption of the photo below which featured himself, his wife and Remi.
