On Monday's 'Ellen", ANNE HATHAWAY said she has "not heard from" KATIE HOLMES since she broke out her Katie Holmes impersonation again on "Saturday Night Live" last month.

She added, "What I really wanted to have happen, because this is the second time I've done Katie, I wanted Katie to come on the show and do me, and I wanted to do this rap about how awesome I think Katie Holmes is."

But Katie is apparently too busy to do that, or to give Anne a call.  Anne says, "She is on Broadway, and killing it on Broadway, so she was busy."  (You can see the clip from "Ellen" here or on YouTube.)
