Maci Bookout and Taylor McKinney welcomed their second child together at the end of last month (the third for Bookout), and on Twitter, nearly all of their Teen Mom OG co-stars sent them congratulatory messages.

After hearing about the exciting news, Catelynn Lowell and Amber Portwood took time to send their well wishes to Bookout and her family.

Meanwhile, Farrah Abraham has stayed completely silent about Bookout's baby news, choosing to instead focus on the opening of her new frozen yogurt venue.

As fans of the series may recall, Bookout and Abraham have been at odds on and off for years, and currently, they appear to be off.

“I don’t judge Farrah or dislike her, but Bentley’s in kindergarten. So kids already ask him about being on TV. And now it’s like ‘Oh, is your mom the one who did a sex tape? Is your mom the one who did a porn?’” Bookout explained to her costars during a scene from Teen Mom OG last year, via Us Weekly.

“There’s no shame in porn,” Tyler Baltierra added. “If you want to go do porn, do porn. But we’re attached to it. At what price are you going to sell your dignity, man? I tell ya, it’d better be a high one.”

Meanwhile, Abraham was heated at her co-stars' issues.

“Hey Maci, why are you here?” she shouted. “I think you should not be here because you don’t want to be here. Bye-bye! My life’s not about porn. I have a child too, I see her every day, and it doesn’t affect her. If it was about Bentley, that would be something else. Bentley doesn’t even know my name.”

Teen Mom OG returns to MTV on Aug. 22 at 10 p.m. A trailer has not yet been released.
