After debuting a huge tattoo across his chest on Instagram that featured Diaz's first name, there's no doubt these two are completely in love and committed to each other.

And a source told E! News that they think her mind has definitely changed on whether she wants children.

"She told Benji she really wants a baby," the source said. "And he said, 'Well, marry me.' He's old-fashioned...Marriage was important to him."

After previously saying, "I've never said never to anything in life. If I wanted kids, at any point in life, I would have them. But I'm certain that if at any point I wanted a child, that child would find its way into my life, whether through adoption, or through being in a relationship with somebody who has a child."

But now that she's married, the source said: "I definitely think she's going to get pregnant right away. I would not be surprised if they're already trying."
