Tim once worked for a station where he interviewed celebrities, and one of those celebrities was Ke$ha (who, as anyone knows, has an admiration for facial hair, and as you can see Tim was rocking some at the time).
In an interview with Mix 101.1 FM's Chrissie Swan and Jane Hall, Tim was asked about his rumored hookup and said the following,
"Let me just wrack my brain... All I'll say about that is I had glitter in places that I didn't know you get could glitter for weeks after."
Then they asked if he knew how old she was and his response was,
"Put glitter on a turd and it'll sparkle."
Alright then. Allegedly She asked for his number after he interviewed her on the Gold Coast and he flew down. She said if he told anyone she would eat him! That certainly sounds like both Ke$ha and Tim.
Here's the time he interviewed her and below is source for his quoted statements:
