Pamela Anderson is entitled to load up on carbs after running the New York Marathon. The “Baywatch” beauty and her new pixie haircut were spotted dining on pasta and salad at Nello on Madison Avenue, with her on-again love Rick Salomon on Tuesday. Anderson completed the race in five hours and 41 minutes, then tweeted a picture of herself lying on a bed covered in bags of ice. And she told Ellen DeGeneres last week, “Yeah, I finished; it was hard. Those last five miles — it was like giving birth and then being told to run as you’re giving birth. It was so much pain in my hips. I don’t know if women are meant to run, especially after having kids.”
