She's having twins!  Brooke Mueller's rep has confirmed that she and Charlie Sheen are expecting twin boys.  “Brooke and I are thrilled! She’s the best stepmom Sam, Lola and Cassandra could ever hope for," Charlie told US Weekly. 

When we spotted Brooke, clad from head to toe in gray sweats, she was leaving a doctor's office in Beverly Hills.  Congratulations to the expectant parents!
