Actress Liv Tyler, who is expecting her third child, finds the experience "fun".

Although she was "tired" because she had a "little cold", the actress recently beamed on the arrivals carpet at an awards ceremony here, reports eonline.com.

She said: "It's amazing. It's so fun. I feel very grateful."

The third child will be her second with fiance Dave Gardner.

She has already seen how wonderful son Milo (whose father is the actress' ex-husband Spacehog rocker Royston Langdon) is with his little brother Sailor, who turns one next month.

"They're so sweet. It's so fun," Tyler said. "My older boy is 11 and it's so sweet to see him with Sailor because there's a big age difference and he just absolutely adores him so much."

Tyler hinted that they already know the sex of the baby, but she laughed and said she was keeping it a "surprise" for the public.

She announced the pregnancy on Instagram on January 8 with a black and white photograph that shows her holding her belly.
