The bubbly, 42-year-old television personality tweeted about the new 'do just before taping.
"Back in the saddle........with a new cut!" she warned Twitter followers, before discussing the transformation with her co-host.
The sleek bob, Kelly wrote later, was inspired by 59-year-old actress Ellen Barkin.
I am obsessed with @EllenBarkin. You are my hair icon. 4eva!— Kelly Ripa (@KellyRipa) September 4, 2013
Though Ripa's new look garnered positive reactions from the Twittersphere, she's not getting much support from mom.
"She goes, 'I don't need to see it to know I don't like it. You know I'm a long-hair girl,'" Ripa quoted her mother as saying.
