"I'm in a great relationship," Charlize told ET's Brooke Anderson on Tuesday at the Las Vegas convention. "I'm really happy."
While the Oscar-winning star said that things were going well, she also admitted that relationships that develop in the public eye can often feel a little awkward.
"You know, that stuff comes out and you always feel a little silly because it's your private life," Charlize said, adding, "[But] my life is in a really good place right now. And I'm just really happy for that."
The star couple was first spotted together in December 2013, but have remained relatively tight-lipped about their relationship with the press.
When asked how motherhood has changed her approach to working and acting, she explained, "It's [about] finding balance."
"It's trying to have the life that you really want, and to feel like you're your own individual," Charlize, 39, continued. "And then also to, you know, be a mom and be there for your kid… I'm just trying to find that balance."
