When the incident was brought up on the "Tonight" TV talk show, Foxx apologised and said: "I didn't mean it maliciously."
Foxx had started talking about Cyrus on his Sirius satellite radio show after someone brought up the singer's recent feud with Radiohead.
Foxx said: "Who is Miley Cyrus? The one with all the gums? She needs to get a gum transplant!"
Foxx noted to Jay Leno that he was doing a routine, saying: "Sometimes as comedians, you know, we go a little too far."
