Actor Josh Duhamel has praised his wife Fergie for being so strong throughout what is her first pregnancy and revealed that he hopes they will have more than one child.

The pair are expecting their first baby, which Duhamel recently revealed will be a boy, together and he explained to EOnline.com that "she's unbelievable. The girl is so impressive."

"You never know how it's going to go. Some girls have a tougher time, some a little easier. Because it's a boy, it's been a really lucky pregnancy in a lot of ways. She's been happy, in good spirits, she looks great. Even at 8 and 3/4 months, she's still in great spirits and looking beautiful. And that just means that she's going to want another one, which is good for me."

Fergie, meanwhile, has now officially changed her name from Stacy Ann Ferguson to Fergie Duhamel. The change came from her desire to "conform to the first name which she is commonly and professionally known as, and has been for many years".
