Robert Downey Jr. Stays Tight-Lipped About Baby Name

Although he recently revealed the gender of the baby he is expecting with wife Susan, Robert Downey Jr. is keeping mum about the names they have picked out for their bouncing baby boy, People Magazine reports.

The actor affectionately referred to his wife's baby bump as "Bubba," as they took the red carpet at the premiere of his latest film, Sherlock Holmes: A Game of Shadows, which she produced.

"If I told you the name, then [Susan] would lop off my head with a machete," Downey, 46, told reporters at the event.

A reporter from Entertainment Tonight asked about names, and Downey said he was "forbidden" from revealing it, joking that the last trimester has been tough on him.
