Jennifer Aniston shows off much blonder hair as she returns to 'The Morning Show' set

The 'Friends' alum stars in the AppleTV series alongside Reese Witherspoon

Jennifer Aniston is back -- in more ways than one.

The actress marked her return to the set of "The Morning Show" on Monday with a snap showing off a fresh new look.

The 51-year-old Oscar winner posted two selfies to her Instagram from behind the scenes with none other than her famed hair stylist, Chris McMillian.

In the silly snaps, Aniston and McMillian pucker up for the camera, and the star's evidently brighter locks can be seen as her tousled waves fall past her shoulders.
