It seems things are getting serious between Terrence Howard and Naomi Campbell.

You read here that he was by Naomi's side when Diddy angrily confronted her at Jermaine Dupri's post-Grammy party Feb. 11.

Now a source tells me the two plan to "come out" as a couple on Oscars night.

"Naomi's new main squeeze is Terrence," says the snitch. "They are making their debut as a couple this weekend and will attend all the Oscar parties together."

Howard was nominated for a Best Actor Academy Award last year, for his role in "Hustle & Flow," but lost to Philip Seymour Hoffman in "Capote."
