Seen & Heard

Lady Gaga has gained 25 pounds and is on a diet. The singer said in a recent interview, "I love eating pasta and pizza. I'm a New York Italian girl. That's why I have been staying out of New York. My father opened a restaurant. It's so amazing... it's so freaking delicious, but I'm telling you I gain five pounds every time I go in there. So my dad wants me to eat at the restaurant, and I'm, like, I've got to go where I can drink green juice." [Us]
