Christina Aguilera and Matt RutlerAs you probably know Christina Aguilera is quite pregnant with her second baby. It's hard to believe that her first child, Max, is already 6 years old. If you are wondering how Max will adapt to going from being an only child to a big brother, well, I think he's going to be great. On Monday, he was out and about with his uber-pregnant mami and made it quite clear that he is super protective of mommy and baby sis and he did it with actions not words.

Wait until you see the adorable picture that Aguilera tweeted out of Max being a little hero. It is too cute!

Isn't that just the cutest thing ever? He is holding his mom's hand and shielding her belly.

Aguilera's second baby will be her first child with her fiance, Matt Rutler. She shares custody of Max with her ex-husband Jordan Bratman.

Congratulations to all. It looks like this is going to be one happy, beautiful blended family! Keep up the good work, Max!
