Suri Cruise, daughter of Katie Holmes (and yes, Tom Cruise), makes her singing debut over the end credits of Katie’s new film, “Rare Objects.” The film opens today in limited release and on amazon.com. I watched it tonight and it’s a lovely piece, the third film directed by Holmes as she peels away more and more layers of her talent for us. Nicely done.

Back to “Rare Objects” in a minute. (Oh? You want to know? Suri, who’s almost 17, has a terrific voice. If she wants to be a pop star at some point, she could pull it off with aplomb.)

I ran into Katie Holmes last night at Newel Antiques on East 61st St. where a little reception was thrown for “Rare Objects” by owner Jake Baer. It’s the most charming antiques store in New York, and they were happy to identify with cards all their rare objects that were used in the film. The great set decorator Beth Kushnick invited me, along with Jill Brooke (flowerpowerdaily.com) so we could see where she gets her amazing ideas. I didn’t realize until I got there that Katie would be there, too, along with some of the cast and production people.

Katie was not the one who told me about Suri singing with the band in the movie. Talk about “dropping the lede”! I only figured it out when I went right home and downloaded the film for a very worth it $14.99. There at the end of the music credits among the musicians, it reads: “Vocals: Suri.” Bravo! Aerial East is the featured singer.

I’ve known Katie Holmes a long time but I haven’t seen her in a long time, either. She’s turning into quite the indie film director, with three under her belt. She did tell me that she and Alan Cumming — who’s in this film — are writing a new screenplay but it’s still hush hush.

What did we talk about? A little about Suri, who’s in high school and “a great kid.” We talked about Katie’s love of theater, how she’s added “director” to her achievements, the difference between theater and film acting, and how much she loved her “Dawson’s Creek” co-star Michelle Williams in “The Fabelmans.”

“She always delivers,” Katie said of Michelle. “She’s going to get that Oscar eventually.”

I was impressed. When I met Katie it was in April 2005 at the opening night of “Steel Magnolias” on Broadway. She’d just moved to New York after having an indie hit with “Pieces of April.” She was learning about the city and excited to start the next phase of her career. Eighteen years later, Katie Holmes is confident, forthright, funny, and the mom of a teenager! Talk about a success story!

Go see it in a theater or download “Rare Objects” from amazon. You won’t be disappointed!
