Actor Daniel Radcliffe says he can't understand why people are so obsessed with him because he lives such a boring life.

The `Victor Frankenstein` actor is always amused when he and girlfriend Erin Darke make headlines when they're out and about because they don't do anything interesting, reports femalefirst.co.uk.

"We're always doing hilariously mundane s**t,` he said.

He added: "They never get me doing anything interesting, so the headline has to be like, 'They bought a yoga mat!' "
