Katie Holmes says it is "wonderful" Nicole Kidman is pregnant.

The former 'Dawson's Creek' actress - who is married to Nicole's ex-husband Tom Cruise - has offered her congratulations to Nicole, who is expecting her first baby with country singer husband Keith Urban.

Speaking at the Los Angeles premiere of her new film 'Mad Money' last night , Katie said: "I'm so happy for her. It's wonderful!"

Katie, 29, also said having Tom and their 20-month-old daughter Suri on set while she filmed crime caper 'Mad Money' with Queen Latifah made the job a "billion times better".

She added: "Having Suri and Tom on set was wonderful. You think you love to do something and then you have the people you love there.

"It makes it a billion times better and you didn't realize you were missing that before. It's like, 'Oh my God, life can be this good!' "

On Monday, Nicole, 40, announced she was pregnant (expecting in July), saying she was both "excited and thrilled".

The 'Moulin Rouge' actress already has two adopted children - 12-year-old Connor and 15-year-old Isabella - with ex-husband Tom.

Katie married Tom in Italy's Odescalchi Castle on November 18, seven months after giving birth to daughter Suri.

Tom and Katie celebrated the premiere of her new movie by enjoying a late night dinner at Cut restaurant.

She's taking the lead - or at least attempting.
