Look out Bello-w!

Daredevil clown Bello Nock hams it up on the high wire yesterday, awing onlookers with a death-defying stunt-walk hundreds of feet over Lincoln Center’s plaza fountain.

The big-top redhead kept those in the crowd craning their necks as he negotiated each step between the portico of the David H. Koch Theater and the roof of Avery Fisher Hall.

Bello, who headlined at Ringling Bros. for eight years, has returned to his roots, the one-ring Big Apple Circus, headquartered at Lincoln Center.
