'Teen Mom OG' Amber Portwood’s Ex, Gary Shirley "Did Not Want Another Kid" With New Girlfriend, Kristina Anderson [WATCH VIDEO]

It looks like Amber Portwood's baby daddy, Gary Shirley is unhappy and regretting some things in his life, including getting his new girlfriend, Kristina Anderson pregnant.

According to Radar Online, Gary has been behaving badly on some recent episode's of Teen Mom OG.

Shirley, 27, the founder of a condom line, appears to not be using his own product and has ended up with another child on the way.

In the most recent episode of the reality show, Gary seemed very upset that he was going to be a father for a second time, and revealed to his daughter, Leah, 6, whom he shares with Amber, that her brother or sister was "an accident."

In the clip below, Shirley reveals to the mother of his first child that he is unhappy about Anderson being pregnant.

Radar revealed that the new baby, another girl, is due in May.

Amber warned her ex to stop flirting with her and told Gary that he "made his choice."

"We're always going to love each other, but there are some things that you do that needs to stop. Don't call me crying, don't talk about our marriage, don't talk about your penis, don't call me asking me 'what I'm doing,"' Amber said.

"You're telling me you don't even want the f***ing kid!" Portwood, 24, yells to her ex.

"I said it was an accident!" Shirley yells back. "I never said that. I said I was not ready for a kid."

Gary tries to redeem himself and explain. "Just like I told Heather, I did not want another kid!" he says to Portwood, as she gets angry.

"I don't care about you, I don't care about Kristina, I don't care about your god d*** kid, I don't give a f*** about your life!" Amber yells.

Do you think Gary was wrong to say he his new daughter was "an accident? Do you think he was wrong for still flirting with his ex, and first baby mama, Amber?
