It's a Julia Jubilee!
"Usually I'm asleep by now," she joked as such pals as Tom Hanks, Denzel Washington and Bruce Willis feted her 20 years in Hollywood (George Clooney, Brad Pitt and Richard Gere sent taped kudos).
"Everybody loves Julia," said Hanks. But Roberts, who turns 40 on Oct. 28, is taken. "The widening of my life—and my hips—is really just the true gift of my husband, Danny, who I would be so lonely without," said Roberts, who told PEOPLE that life as the mother of "three amazing children" is "enchanted." Her birthday wish? "More of the same!"
