Ke$ha 'romancing Australian drummer'

Ke$ha is reportedly romancing an Australian-born drummer.

According to E! Online, the 'Tik Tok' star went public with Alex Carapetis at the Music Lounge at the Lollapalooza festival over the weekend.

"They wouldn't stop making out! They have natural chemistry and are always laughing," claimed one eyewitness.

Carapetis, who has toured with Nine Inch Nails in the past, is alleged to have moved from his homeland to Los Angeles to further the romance.

Ke$ha - who recently scooped three MTV VIdeo Music Award nominations - previously revealed that she is attracted to men who are "funny " and "low-maintenance".
