Julia Roberts made her official debut as Lancome's global ambassador this week. So what does she think of her new gig? "It's kind of like every girl's dream," Roberts told WWD. The mom of three also admitted that her primping habits changed drastically when she became a mother. "It kind of comes to a screeching halt," she said. But her new role seems to be changing that already. Roberts looked gorgeous at the Golden Globes, thanks in part to the splash of color on her famous lips courtesy of Lancome's L'Absolu Rouge Lipcolor in Coquette. The actress admitted sitting next to Sir Paul McCartney at the award show was a highlight, although her phone began beeping non-stop. "It was so embarrassing!" Roberts said of the texts that came through. And what were friends saying? "OMG I can't believe you're sitting next next to Paul McCartney!"
