The 30-year-old star got to meet Keith Richards - who is named after The Rolling Stones guitarist - in her job as a judge on 'Australia's Got Talent'.

After the reptile and his handler auditioned, Kelly got to hold the slithery serpent and after spending a few minutes with Keith around her neck she was besotted with the animal.

Kelly even gave the lucky snake a kiss as she held him gently in her hands.

Posting a photo of her puckering up to the snake on Instagram, she included the caption: "I can't believe I fell so deeply in love with a today. Thank you @gottalentau for another work day filled with surprises! (sic)"

Another post about Keith read: "I had the best day hanging out with #KeithRichards (sic)"

The former 'Fashion Police' star - who is currently single - has been Down Under shooting the audition stage of the TV talent show for the last few weeks.

Kelly is joined on the judging panel by Sophie Monk, Ian 'Dicko' Dickson and Eddie Perfect.
