She's yet to flash her engagement ring in public, but Jessica Biel is revealing something new: bangs!

The New Year's Eve actress, 29, rocked a fresh hairstyle while catching up with her former 7th Heaven co-star Beverley Mitchell, 31, in Hollywood, Calif. Saturday.

Wearing a backless gray sweater tucked into a black maxi skirt with orange sunglasses and a Chanel purse, the slim star appeared to have left her bra at home.

Justin Timberlake, 31, proposed to Biel during a snowboarding vacation in Jackson Hole, Wyoming in late December.
