Bentley’s a big brother! Teen Mom OG star Maci Bookout welcomed a baby girl on Friday, May 29. The Tennessee native and her longtime, live-in boyfriend Taylor McKinney named their baby girl Jayde Carter. 

"Jayde made her grand entrance at 1:59pm today," the proud mom tweeted Friday. "She weighed 7lbs 15oz at birth. She is beautiful and as healthy as can be! @tmon3yy."

Teen Mom costar Tyler Baltierra added: "HUGE congratulations to my friends @MaciBookoutMTV & @tmon3yy on the arrival of their daughter Jayde! Me & @CatelynnLowell are so happy 4 u!"

Bookout, 23, already shares her 6-year-old son Bentley with ex Ryan Edwards. 

Prior to giving birth, the new homeowner was dealing with some big issues. 

“a water leak in ur house on memorial day weekend (nobody is working) & ur having a baby in less than a week. perfect. im gonna lose my mind,” Bookout tweeted on May 24.

She and McKinney bought a home together on the May 25 season finale of Teen Mom OG, and were in the process of moving in when the show wrapped. Though Bookout was eager to get engaged to McKinney, the bearded biker seemed determined to keep his proposal a surprise, teasing in the finale, "Guess you'll have to stay tuned." 

Earlier in the season, Bookout made the decision to keep her young son off the MTV series after the producers brought back adult film star Farrah Abraham. She continued to film the show, keeping Bentley away from the cameras. 

On May 20, however, she offered a precious update about the little baseball pro, tweeting, “i cant believe today is benny's last day of kindergarten.”
