LOS ANGELES - Being the mother of Tom Cruise's baby daughter has been so much fun that Katie Holmes tells "Entertainment Tonight" she's ready to have more children.

"We're having the best time, it's so amazing," Holmes, 28, said of the year she and Cruise have spent largely out of the spotlight. She gave birth to the couple's first child, Suri, in April 2006.

"Yes, definitely," she told the TV program when asked about the possibility of more kids. The interview airs Monday.

Cruise and his ex-wife, Nicole Kidman, have a 12-year-old son and 15-year-old daughter, and Holmes said the role of stepmother is one she relishes.

"The kids are so sweet, they're so great with Suri and she lights up when she sees them," she said. "We have so many kids in our house, there's always this wonderful chatter and the great noise of kids."

The actress, who recently returned to work filming the movie "Mad Money" with Diane Keaton and Queen Latifah, said her 44-year-old husband has played a key role in making the transition to motherhood an easy one.

"He's a great father and so it came to no shock that when we had Suri he was amazing with the baby," she said.
