It looks like Katie Holmes has been bitten by the baby bug. According to friends, the mom of 2-year-old Suri wants to have another baby soon. "Katie said she's got the itch," a friend tells E! Online. "Now that Suri is more toddler than baby, she said she misses having an infant in the house. And, of course, she thinks Suri would make a great big sister." As for what dad Tom Cruise thinks? "He said if Katie wants to make another baby, she doesn't have to ask twice," adds the pal. "He always wanted more. It was Katie who has been holding off. Until now."
