Since becoming a spokeswoman for Weight Watchers in 2010, Jennifer Hudson has been happy to show off her trim and fit physique. The American Idol alum went from a size 16 to a rumored size zero. And as she plans her new album release in 2014, the singer is also flaunting her slimmed-down figure in music videos. 

On Dec. 16, she was spotted filming in Los Angeles wearing a sexy black leotard with a black leather jacket overtop. An ode to "Single Ladies," perhaps?

In Hudson's own music video look, the Oscar winner's toned legs stole the show in the revealing ensemble, and she was rocking her new pixie cut in addition to a series of earrings up her left ear. 

Her recent single, "I Can't Describe (The Way I Feel)," has a lyric video, but no official music video yet, so this look could be part of the video for the single. 

In Oct. 2013, Hudson told Rolling Stone that her third studio album would hit stores in 2014. 

"I do know that I want to Jennifer-ize this album, meaning I want you to get a sense of who I am as a person, not just as a celebrity, or a brand, or a public figure. That’s what I want this music to reflect," she told the magazine.
