After 50 years in television, it's fair to say that Kerri-Anne Kennerley, 65, has seen it all.
However, the behavior of Studio 10 host Sarah Harris on Wednesday managed to floor the blonde industry veteran.
During an ad break on the Network 10 program, Sarah sang, clapped and danced along to a high-energy clip from teen cheerleader film Bring It On while seated in her presenter's chair.
That look! Kerri-Anne Kennerley, 65, appeared very unimpressed with Sarah Harris (pictured), 37, who danced and clapped along to a clip from teen cheerleader film Bring It On while hosting Studio 10 on Wednesday
Sarah, 37, appeared to know all the words to the upbeat tune as Kerri-Anne looked on beside her, aghast.
After clocking Sarah's boss moves up close, Kerri-Anne looked around the room in mute bewilderment.
