Paris ? Actor Tom Cruise said he and girlfriend Katie Holmes are engaged, after he popped the question early Friday morning atop the Eiffel Tower.

Actor Tom Cruise holds the hand of his fiancee, actress Katie Holmes, who sports her new engagement ring Friday.

Cruise, speaking at a Paris news conference with Holmes, said: “Yes, I proposed to her.”

The couple often shared smiles and blushes as Cruise turned to look at her, with a massive diamond ring on her finger.

“It was early this morning at the Eiffel Tower, so I haven’t slept at all,” he said. “Today is a magnificent day for me, I’m engaged to a magnificent woman.”

Asked why he chose the famed Paris landmark, he said: “I’ve never been to the Eiffel Tower. It’s Paris, it’s a beautiful city, it’s very romantic.”

Cruise said no date for a wedding has been set: “We haven’t discussed that – one step at a time,” he said. “Let’s see. We’re not sure.”

Cruise, 42, was in Paris to promote the French release of the Steven Spielberg film “War of the Worlds” next month. He and 26-year-old Holmes went public with their romantic relationship in April.

Holmes did not speak to reporters, but at one point, Cruise whispered to her: “Are you OK?” Afterward, the two hurried into a car before leaving for a promotional event in Marseilles, southern France.

Holmes was in London earlier this week to promote her new film, “Batman Begins.” She had also dismissed accusations that the couple had staged a relationship for publicity.
