Irina Shayk's pregnancy isn't slowing her down...that much.

But the model, who has been nonstop traveling since leaving Paris after the Victoria's Secret Fashion Show, is starting to feel the side effects of her pregnancy. "Irina is doing pretty well. She has some food cravings because she's pregnant," a source tells E! News. "She is not the kind of woman to count calories, but she has been taking it easy. She's also exercising in moderation."

Even though the on-the-go lifestyle is taking a toll on her energy levels, it's not affecting her relationship with Bradley Cooper. "She is more tired than usual. She has been traveling a lot and hasn't had time to see Bradley but plans on seeing him very soon," the insider explains. "They are in communication a few times a day. They are really happy and can't wait to have their baby."
