Julia Roberts shows off photos of her five-month-old son

Hollywood actress Julia Roberts gushed as she showed off a photo of her five-month-old son for the first time last night.

The 'Pretty Woman' actress told Oprah that despite shutterbugs best efforts nobody had yet caught a glimpse of her son Henry born in June.

"There's been a lot of curiosity but there's not been a picture of him. I thought I would just show everybody,"

Julia said as she turned over the picture of her baby. The 40-year-old actress and her cameraman hubby Danny Moder also have twins, Hazel and Phinnaeus, who turn 3 on November 28.

Roberts said the birth of the couple's third child would probably be the last addition to their family.

"It just completed us," Roberts said.

"We're complete. We're a good five-some."

She joked: "I have to say, little Henry's the sweetest child known to mankind - I think I can say that objectively."

Julia and Tom Hanks appeared on Oprah to promote their upcoming film "Charlie Wilson's War."
