Sandra Bullock Tears Up Talking About Her 'Sweet Little Man' Louis

OK, we'll admit it ... Louis Bullock melts our hearts.

In a new interview with E!'s Giuliana Rancic, Sandra Bullock gushes over her "sweet little man" and even tears up at the mention of his name. When asked why he's "the cutest baby," Bullock says paparazzi photos don't do him justice.

"Isn't he usually giving stink eye?" she asks before adding, "He's in a situation where he's not liking that someone's there with a camera. But he's giving stink eye because he doesn't want anybody messing with his mom. That's what breaks my heart, because he's doing it … he's like, 'Don't get near my mom.' He doesn't know why those people are there but he senses -- any time any man gets near me, he's like, 'Dude, don't get near my mom.' So when there's about eight of them, it's the same thing. It's like he doesn't like that energy that's coming."

Bullock admits that it's nice having a little guy around to protect her, but she's also learning a lot of interesting things about men in general.

"He's all dude. He's just a dude. And I'm learning a lot about being a dude! Apparently when you sleep, your hand needs to be down your pants," she jokes. "I didn't know that as a woman! What are we doing wrong as women ... should we be doing that?"

Still, despite all the funny quirks of motherhood, Bullock admits that it has been a life-changer for her, in more ways than one. That's probably why she would love to have more kids ... if "the boss" Louis would allow it.

"I thought I was the most hardened, jaded individual I knew. And I can be brought to a mess in seconds," she explains of being a mom. "It's like you go, 'Oh, I grew a heart.' I get weepy all the time, it's embarrassing … but that's it, you just realize that you are walking love."
