Julia Roberts and Lindsay Lohan were under doctors' orders to rest up after both stars were admitted to L.A. hospitals. Roberts, 37, who is expecting twins in January, checked in Oct. 23 after experiencing contractions and remains hospitalized. Though her condition isn't serious, she has to stay off her feet until she gives birth. Meanwhile, Lohan, 18, was released Oct. 26 after five days of treatment for a severe fever. "She was wiped out," her publicist told PEOPLE.
