Megan Fox became a second-time mom on Thursday.

The 27-year-old actress, who is married to "Beverly Hills 90210" star Brian Austin Green, revealed the news to TooFab. This is the second boy for the couple, which means Megan Fox is now outnumbered by males at home.

Their first son is named Noah. Brian Austin Green also has another son, an 11-year-old named Kassius, from a previous marriage.

Green and Fox did not give any more details about their new son.

The couple announced they were expecting in August, but not much more was revealed.

Though Brian Austin Green did speak to HollywoodLife in September to talk about his wife. "She is doing great, she did great the first time around. But I wouldn't wish the experience on anybody, I couldn't do it! I couldn't make a baby. It's unbelievable! I do whatever she asks for and I say 'Yes' no matter it may be."

That's a great thing for Fox who told ABC News that she had a rough first trimester, and that she didn't even have time to compare how the two pregnancies differed, though she previously said her first pregnancy was also rough.

"I don't have time to think about it," she said. "I have a 1-year-old running around. And then when you're working like 16 hours a day, there's no time for you at all."

Other than that, Fox didn't share much more. There we no pictures on social media or details about the sex.

As a matter of fact, she barely made any public appearances. One of her last events was the International Day for the Elimination of Violence Against Women at the end of November in New York.
