Fergie is enjoying her pregnancy while holidaying in Sydney, Australia.
The Black Eyed Peas singer, real name Stacy Ferguson, is expecting a baby with husband Josh Duhamel.
The 37-year-old star made the announcement via Twitter on Monday.
“Josh & Me & BABY makes three,” she wrote, adding the hashtag, “#MyLovelyBabyBump”.
Fergie and Josh married in January 2009 after five years of dating.
Last September she denied the rumours during an appearance on America’s Rachael Ray Show.
“[People ask if I'm pregnant] every time I fluctuate a few pounds. Like right now, I’m a couple pounds up,” she said, explaining, “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.”
