Fergie, 37, and her husband Josh Duhamel, 39, want children, but right now, the married couple aren't expecting.
The singer, known for her taunt physique, admitted that she put on a few pounds, and that's why everyone has been saying she has a bun in the oven.
"[People ask if I'm pregnant] every time I fluctuate a few pounds. Like right now, I'm a couple pounds up," the Black Eyed Peas singer said on the "Rachael Ray Show" on Sept. 20, according to Us Weekly. "Sometimes I go a couple pounds down and I wear the clothes that are more fitted, but people kind of look at me because they're expecting [that] it's that time. We do hope for children and that will be coming up, but it's not yet."
The married couple of three years are just enjoying each other's company.
Duhamel just wrapped up production of the film "Safe Haven," who he plays alongside Julianna Hough.
Fergie feels comfortable enough around Duhmel to dress down, and he doesn't mind.
"I love [wearing] sweats," Fergie said, according to Us Weekly. "I steal Josh's T-shirts. It's fun! They're baggy and he likes it."
But when it's date night, she wants to preserve the fantasy.
"I hate when he comes in in the middle of me getting ready. It just ruins the whole thing," Fergie said with a life. "I'm always like, 'Get out!' You want to come out and present."
On the "Rachael Ray Show", the blonde wore slimming black Givenchy leggings and a top, donning a sheer shirt with green and yellow prints. She also paired the outfit with steel toe heels from her own fashion line and round lens sunglasses as she left the New York City studio.
During the show, she promoted her new Wet N Wild nail polish.
