It's a boy for Robert Downey Jr. and his wife of six years, Susan Levin!
Appearing on the "Tonight Show With Jay Leno" Monday night to promote his upcoming movie, "Sherlock Holmes: A Game Of Shadows," the actor flaunted his wicked sense of humor by teasing the late-night host before dishing out major news.
"I am not permitted to discuss it. I can't say a word... We're having a boy!" Downey blurted out, to loud audience cheer. The couple, who are expecting to give birth in February, first announced their pregnancy in mid-August.
Downey has an 18-year-old son, Indio, from his first marriage to actress/singer Deborah Falconer, which leaves us hopeful that he'll name his mini "Iron Man" something totally obvious: Robert Downey III.
CORRECTION: A previous version of this article misstated the name of Downey Jr.'s first son as "Idio." He is named Indio.
