"It's a balancing act," she told to reporters at the L.A. premiere of the new film Wednesday.
The Black Eyed Peas singer arrived at the premiere on the arm of hubby Josh Duhamel wearing a tight black mini-dress. The couple appeared cozy, showing no signs of strain after a woman recently claimed she had an affair with Duhamel, which a rep for the actor called ridiculous.
And to prove his devotion, Duhamel was attentive and affectionate while posing for photos with his wife, wrapping his arm around her and kissing her forehead before heading into the theater while she chatted with her costars Penélope Cruz and Nicole Kidman.
Inside the theater, Duhamel was doting as dozens of friends and admirers offered Fergie their well-wishes before the screening. He wrapped his arm around her shoulders as they took their seats.
It was the first time Duhamel watched his wife perform on the big screen, an experience that was nerve-racking.
"I have to say that it was very intimidating flying there, going to my dressing room and going to the set – but once I got there everyone was so normal and down to earth that it was cool. The ice was broken," Fergie said about working on the movie. "When I walked in it was basically me and Daniel-Day Lewis and … I'm having to be at the piano, singing 'Be Italian' in full voice in front of him and about a hundred other people.”
She added: "I had to get over it real quickly!"
