Fergie aka Stacy Ferguson at The 50th Annual Grammy Awards held at the Staples Centre - Arrivals, Los Angeles, California - 10.02.08

The singer - real name Stacy Ferguson - sparked speculation she was pregnant after flaunting a more shapely figure while dining out with her beau at Hana Sushi in Santa Monica earlier this month (Mar08).

But the 32-year-old's representative has laughed off the reports, insisting the star is "not preggers".

Duhamel's spokesperson also denied the pregnancy tales, explaining, ""It's not true. She is not pregnant."

Fergie has spoken out on her plans to settle down before, insisting the only thing she is considering nurturing is her next solo project.

She says, "I want a marriage and family on the one hand, and on the other hand, I want to do another solo album, one where I can have time to sit in the studio and really nurture it."
