Maci Bookout is no longer a teenager, but she has become a mother for the second time. The “Teen Mom OG” star gave birth to her second child, Jayde Carter. She made the announcement over Twitter on Friday night that she had gone into labor earlier that afternoon.

Although this is Bookout's second child, Jayde is her first with boyfriend Taylor McKinney. The motocross racer appeared on “Teen Mom OG” this year along with Bookout’s first child, Bentley, 6 (whose father is Ryan Edwards). Bookout and McKinney aren’t married, but the Tennessee resident said she wouldn’t rule it out.

“We definitely want to get married and we’ve talked about it a lot,” Bookout, 23, told People in March. “But we aren’t trying to cram it all in at one time. After the baby comes and we get settled in with parenting two children, then that will definitely be our next step.”

The MTV reality show's finale aired last Monday, but Bookout's co-stars still keep in touch when the cameras are off. Many of them took to Twitter to send their wishes along. Bookout has been on MTV’s “Teen Mom” franchise since it premiered in 2009 along with Catelynn Lowell, Tyler Baltierra and Amber Portwood.

Baltierra sent along a message on behalf of him and his fiancée, Lowell.

Baltierra also let McKinney know that fatherhood would be an amazing journey. Baltierra is the father of two: Carly, who he and Lowell gave up for adoption in 2009, and Novalee, who was born in January.

Portwood sent her best wishes to Bookout on Saturday as did “Teen Mom 2” star Kailyn Lowry.

However, one "Teen Mom OG" co-star was silent on social media. Farrah Abrahams did not send any public messages to Bookout, which is probably unsurprising to many fans. The two were feuding throughout Season 5.
