Robert Downey Jr. sat on Jay Leno's couch on Monday, dropping some big news concerning his unborn child due in late February.
After laboring over how he's not currently at liberty to reveal the baby's gender, the Golden Globe winner feigned accidently spilling the beans.
"We're having a boy," Robert blurted, covering his face in pretend shame.
Robert and producer Susan Downey have been married for six years. Although Robert has one child from a previous marriage, this is Robert and Susan's first child together.
Robert's newest film Sherlock Holmes: A Game of Shadows hits theaters December 16. Watch Robert's entire Tonight Show interview tonight on NBC.
