Fergie shares her son with ex Josh Duhamel, 51.

While appearing on The Jess Cagle Show last September, Duhamel — who welcomed his first baby with wife Audra Mari in January this year — opened up about his ex-wife Fergie's support after he revealed his exciting news.

"Thankfully, Fergie's an amazing woman, she really is," said Duhamel. "She's taken Audra in. It could be much worse."

"That's the thing, you never know how these things are going to go. But because she's such a kind-hearted person, she really, truly is, she only has love for Audra. I can't believe how excited she is for us. It could be a lot worse. I've seen it. I've lived it. And thankfully we have a really civil situation."

When Duhamel and Mari announced that they were expecting a baby together, Fergie was one of the many commenters who left well wishes for the couple.

Writing underneath the post, Fergie made sure to send her congratulations, commenting, “I am truly happy for you guys???? Axl can’t wait to be a big brother."

In a September interview, the Transformers star opened up to Parade about how his son was responding to the news that he was going to get a little brother.

"He's like, 'Wait, now, am I going to be — You're still going to love me, though, too, right?' " Duhamel said of an inquisitive Axl.

“I was like, 'Of course, I'm going to still love you.' And he's like, 'I'm still going to be your firstborn son, though, right?' I'm like, 'Yeah, you're still the firstborn son!' ” the Shotgun Wedding actor added.

"He's a really sweet kid. And he loves babies!" Duhamel said. "I was the same way at his age. I just have always loved babies. There's something about them. And he's really good with younger kids. So I think he's going to be a great older brother."
