Katie Holmes fueled another round of pregnancy rumors at the L.A. premiere of husband Tom Cruise’s new drama Lions for Lambs Thursday.

A glowing Holmes, 28, appeared to be sporting a mini bump as she worked the red carpet in a one-shouldered, silk charmeuse Monique Lhuillier gown.

Though she didn’t address questions about a possible pregnancy, the actress and her husband — who will celebrate their one-year wedding anniversary November 18, were happy to give the crowd a display of their mutual affection, as Cruise, 42, whispered to his wife and softly kissed her ear as they made their way into the theater.

“Tom kissed Katie a few times lightly near her ear and whispered to her,” a witness told Usmagazine.com. “She would turn to him and smile.”

Cruise recently said he and Holmes could handle having another little one around.

He told Entertainment Tonight November 1 that he and Holmes have already mastered raising their 18-month-old, Suri.

He said they share parenting duties “just like everybody else, you just work it out. You make it work. We’ve gotten pretty good at organizing everything.” Laughing, he added, “I don’t sleep much anyway.”

This isn’t the first baby No. 2 rumor for the duo: She had blogs a buzz when she wore an an empire-waist Balenciaga top at a Berlin airport in October. Her rep told Us at the time: “She is not pregnant.”
