Hilary Duff blonde leather sunglasses gym workout

Lookin' hot Hil!

Hilary Duff got up bright and early to head to the gym in L.A. today, and the actress looked stunning with her new super blonde tresses blowing in the wind! The newly single starlet donned a leather jacket as she made her way into her sweat session, and we've never understood this trend. Don't celebs like Nicole Richie perspire during their fitness routines?!

The former Lizzie Maguire star has a lot to smile about these days! The 26-year-old star just celebrated son Luca's second birthday, and she has been nonstop in the studio preparing fresh tunes for her upcoming album.

The singer Instagrammed the below picture of a lyric sheet the other day, and we're dying to know who she's penning these words for!
