Despite Andy being in a long-term relationship with girlfriend Rebecca Harding, The Voice coach seemed clearly infatuated with the dark-haired presenter at a Channel Nine event they both attended in Sydney recently.
She was apparently ‘besotted’ with him, and clearly had her sights set on collaring him.
"Delta made a beeline for Andy as soon as she spotted him in the room," a source revealed to New Idea, adding that they spent time locked in conversation.
"They looked to be talking pretty intimately, before Delta was pulled away."
It’s not the first time they’ve appeared to be getting up close and personal at an event either, and this was no exception as she – who has been single for quite some time – seemed to be eyeing Andy adoringly and found it almost impossible to turn away her gaze.
"When Andy took to the stage, Delta was front and centre looking lovingly at the comedian," the source said.
"She couldn’t take her eyes off him – it looked like she was absolutely besotted with him!"
It’s not the first time Delta has become a little heated under the collar during the show.
Fans recently slammed her for ‘objectifying’ 24-year-old personal trainer Brock Ashby when she flirted up a storm with the hunk.
Last year Delta was also seen getting all gooey over Northern Beaches lad Tim Conlon, when she ran up onto the stage and kissed him after his performance.
