Fergie appeared to be in quite a sour mood as she left a private residence in Los Angeles yesterday (September 4).

Dressed in a billowy t-shirt, denim short shorts, matching suspenders and a fedora, the Black Eyed Peas frontwoman ignored the flurry of compliments from the paparazzi as she began her day of errand running.

Meanwhile, it appears an unlikely musician is currently crushing on Fergie — folk rocker Jason Mraz!

“I am crazy about Fergie,” he told E! during the Outside Lands music festival in San Francisco last weekend. “I always have been. I got to meet her recently. We had this awkward little chat because the whole time in my mind I’m like ‘Let me see those humps.’ I want it, but she’s married.”
