Ventriloquist stuns America's Got Talent judges with live tribute to Olivia Newton-John

As celebrities around the world continue to honour the beloved Olivia Newton-John after she passed away earlier this month, one America's Got Talent contestant has also paid a heartful tribute to the Australian icon.

Celia Munoz is a ventriloquist from Madrid, however, her act is a little different in that she doesn't use a puppet.

Taking to the stage, the trained opera singer belted out a heartfelt rendition of 'Hopelessly Devoted To You,' first crooned by Newton-John's character, Sandy Olsson, in Grease.

The judges and viewers loved the tribute to the late actress, with Heidi Klum saying: "I love the tribute to Olivia Newton-John. I love that."

Klum also admitted that she can't understand how Munoz was able to eat and do ventriloquism at the same time. 

'Hopelessly Devoted to You' was a major hit for Newton-John in 1978, reaching the number three spot on the US Billboard Hot 100 and number 20 on the country chart.
